Katianna Stoermer Coleman: Zendaya’s Older Sister and Life Away from the Spotlight
Most people first hear the name Katianna Stoermer Coleman in the same sentence as her younger sister, Zendaya, one of the biggest stars of her generation. Yet the woman herself has never chased the attention that comes with that connection. Among the many celebrity stories that start with a famous name, hers stands out for the opposite reason: Katianna Stoermer Coleman has spent her adult life keeping her distance from the cameras, raising her family in Oakland, and letting her sister take the spotlight while she stays firmly in the background.
Katianna Stoermer Coleman is the older half-sister of Zendaya, the Emmy-winning actress known for Euphoria, the Spider-Man films and Dune. The two share a father, Kazembe Ajamu Coleman, but they have different mothers, and Katianna comes from her father’s earlier relationship. Zendaya has said more than once that her big sister shaped who she became, and that single fact tells you more about Katianna than any biography site’s guesswork ever could.
This article looks at what is actually known about Katianna Stoermer Coleman, from her Oakland childhood in a big blended family to her close bond with Zendaya and the private, family-centred life she leads today. Where the sources disagree, and they disagree often, the disagreement is noted, because a careful account should say so rather than pick a side without proof.

Who Is Katianna Stoermer Coleman?
Katianna Stoermer Coleman is an American private citizen who happens to be the older half-sister of one of the most famous young actresses in the world. Katianna Stoermer Coleman is not an actress, a singer or a social media star, and she has never tried to be one. Her public identity begins and ends with her family, and that is exactly how she seems to want it.
She is the daughter of Kazembe Ajamu Coleman, a former teacher and stage manager who later became Zendaya’s manager. Her father had five older children from a previous relationship before Zendaya was born, and Katianna is one of them. Zendaya, whose full name is Zendaya Maree Stoermer Coleman, is the only child of Kazembe and his wife Claire Stoermer, which makes Katianna her half-sister rather than a full sibling. The distinction matters to the family tree, but it has never seemed to matter much to the family itself.
What makes Katianna Stoermer Coleman interesting is not a career or a public profile. It is the role she has played inside one of Hollywood’s most grounded families. While her younger sister went from Disney Channel shows to the biggest film franchises in the world, Katianna stayed in Oakland, built a family of her own, and became the person Zendaya points to when she talks about what kept her steady. That is a quiet kind of influence, and it is the thread that runs through everything reliable that has been written about her.
Growing Up in Oakland, California
Katianna Stoermer Coleman grew up in Oakland, California, a city across the bay from San Francisco with a long history of music, sport and street-level culture. Oakland is where the Coleman family put down roots, and it is where Zendaya spent her own childhood too, years after Katianna’s. The sisters grew up in the same city but in different households and at different times, which is one reason their shared story is really two stories that overlap rather than one.
The household Katianna Stoermer Coleman grew up in was a working one. Her father, Kazembe, worked as a teacher and in theatre, and the family lived close to the arts without being part of the entertainment industry in the way people usually mean it. Theatre, school and community life shaped the family’s days, and the children grew up around scripts, rehearsals and classrooms rather than red carpets. That background shows up again and again in the way Zendaya talks about her family: as a big, grounded group of people who look out for one another.
Katianna Stoermer Coleman was already an adult by the time Zendaya was born on 1 September 1996. The age gap between the sisters is one of the reasons their relationship looks more like a mentor and a younger sister than two siblings growing up side by side. Katianna had a life of her own by the time her little sister arrived, and she became a steady presence in Zendaya’s childhood rather than a playmate in it. In a 2019 profile of Zendaya, Kizzi herself told Vogue that “everyone pitched in” during their childhoods, a small line that says a lot about how the family worked.
Oakland has stayed home for Katianna Stoermer Coleman. Reports place her there still, living quietly with her family, and nothing in the public record suggests she has ever wanted to leave it for Los Angeles or anywhere else in the industry. She grew up in the city, she raised her children there, and the city seems to suit the life she chose.
The Coleman Family: Six Siblings
To understand Katianna Stoermer Coleman, it helps to understand the family she belongs to. Zendaya is the youngest of six children. Her five older half-siblings, all from her father Kazembe’s previous relationship, are three sisters, Katianna, Annabella and Kaylee, and two brothers, Austin and Julien. The six of them share a father but not a mother, and Zendaya is the only child of Kazembe and Claire Stoermer.
Each of the older siblings has taken a different path. Austin Coleman has worked as an actor and voice actor, and he is the sibling most often seen at public events with Zendaya. Julien Coleman, sometimes called EZ, has stayed largely out of the public eye, and his daughter Ezenia, nicknamed Zink, is one of Zendaya’s closest nieces. Annabella and Kaylee Coleman keep low profiles of their own, and Kaylee, the youngest of the half-siblings, is the closest in age to Zendaya. Katianna Stoermer Coleman, known to the family as Kizzi, is widely described as the oldest of the group, the one the younger siblings looked up to first.
The family is a blended one in the fullest sense, and the Colemans have never made a secret of that. Kazembe’s children from his earlier relationship and his daughter with Claire Stoermer grew up as one extended family, with nieces and nephews, shared holidays and a network of support that Zendaya talks about often. In interviews she has described her nieces and nephews as her “borrowed children”, joking that she gets to have fun with them and then give them back to their parents, and she has said she thinks about her little nieces and nephews first when she makes decisions about her public life.
The children’s mother, Claire Stoermer, is part of this story too. A former teacher at Fruitvale Elementary School in Oakland, she worked in theatre as well, and she later ran a jewellery line called Kizzmet Jewellery, made from crystals such as amethyst, hematite and chrysocolla. Kazembe and Claire divorced in 2016, but both stayed close to their daughter, and the wider family stayed close to one another. That closeness is the backbone of the family, and Katianna Stoermer Coleman sits at the older end of it, the sister who was there before the fame and stayed after it arrived.
Kizzi and Zendaya: A Close Bond
The clearest window into who Katianna Stoermer Coleman is comes from Zendaya herself. In a 2015 interview with TIME, the actress praised her father for his strength and her mother for being a “sheroe”, but she said it was her older sister who had the biggest impact on her youth. “I look up to my big sister and realize the influence she’s had on me and making me a better person,” Zendaya said. “Having such a big, grounded family, I realized as you get older how important that is.” The remark is widely understood to refer to Kizzi, the sister Zendaya calls her biggest influence, and it is the single most quoted thing anyone in the family has said about her.
Zendaya has returned to the theme of Katianna Stoermer Coleman’s influence in other interviews. She has described her family as the thing that keeps her steady in an industry that pulls young stars in every direction, and she has pointed to her older sister as the example she measured herself against as a teenager. That is a lot of weight to put on one sibling, and it says something about the kind of person Katianna is: not a celebrity, not a manager, not a public figure, but a sister whose judgment mattered.
The two have been seen together at public events over the years, and Katianna has appeared in family photos and in Zendaya’s social media from time to time. Katianna Stoermer Coleman is the sibling most often photographed alongside the star, and the closeness between them is plain in those pictures. She has also taken part in family moments that fans remember well. In March 2017, Zendaya treated Kizzi and her nieces to a Harry Potter-themed birthday trip to Universal Studios Hollywood, a day out that Zendaya later wrote about on Instagram as earning her “major auntie points”. It was a small, joyful moment, and it fits the picture of the family that comes through in every reliable account: generous with each other, close across a wide age gap, and fond of the ordinary things.
That bond runs both ways. Katianna’s daughters grew up with Zendaya as their famous aunt, and Zendaya has often babysat for them, going back to her Disney Channel days. She has talked about how much she loves being an aunt, and how the children keep her connected to the family while she works far from home. For Katianna Stoermer Coleman, having a sister who is one of the most recognisable faces on the planet could have meant a life lived in the glare. Instead it has meant a quieter one, with the fame kept at arm’s length and the family kept close.
A Mother and a Private Life
Katianna Stoermer Coleman is a mother, and it is the part of her life that seems to matter most to her. Zendaya has spoken about her nieces, saying in a 2019 Vogue interview that Katianna has two daughters, Imani and Isys. The girls were teenagers by the time that interview was published, and Zendaya has often mentioned how much she enjoys being their aunt. The family has kept the girls out of the public eye for the most part, and Katianna has never used them, or herself, to build any kind of public profile.
There is one wrinkle in the record here, and it is worth stating plainly. While the Vogue interview names two daughters, Imani and Isys, a later PEOPLE profile describes Katianna as a mother of three daughters. The two accounts do not line up neatly, and no official statement from Katianna herself settles the question. This article gives both figures and notes the conflict rather than choosing one without proof, because the honest position is that her family life is private and the public record is incomplete.
What is consistent across the reliable accounts is that Katianna Stoermer Coleman lives with her husband and children in California and keeps her household away from the entertainment world. Reports describe her home life as stable and settled, and Zendaya has said that one of her sisters lives in Los Angeles with her two daughters and her husband, though some reports place Katianna in Oakland. Either way, the picture is the same: a family home, a husband, children, and a life built around them rather than around a career in public.
Katianna Stoermer Coleman has no verified public social media presence, and she gives no interviews about herself. That silence is a choice, and it is one that sets her apart from many celebrity siblings, who often build brands from the connection. Katianna has never done that. No product line, no reality show, no podcast, no memoir. The public record of her life is mostly what Zendaya has said about her, plus the occasional family photograph, and she seems content for it to stay that way.
Life Away from Hollywood
Katianna Stoermer Coleman has no career in the entertainment industry, and every reliable source agrees on that point. Unlike her father, who worked as a stage manager and later managed Zendaya, and unlike her brother Austin, who has acted, Katianna has never worked in front of a camera or behind one in any public way. Her life is a private one, and her work, whatever it is, is not something she has ever discussed in public.
That absence of a public career has created a vacuum, and the internet has filled it with guesswork. Some low-quality biography sites describe Katianna Stoermer Coleman as a social media personality or even a TikTok star, but there is no verified account, no public following and no evidence to support the claim. Others give her a job title or a salary, and those are inventions too. The honest position is simple: her occupation is not publicly documented, and anyone who claims to know it is guessing.
Katianna Stoermer Coleman’s privacy extends to almost everything else as well. There is no confirmed birth date for her in any major outlet, no confirmed height, no confirmed school, and no confirmed net worth, though some sites quote figures such as $500,000. None of those numbers comes from a credible financial source, and this article does not repeat any of them as fact. A private person is entitled to keep those details private, and the right response is to say so rather than to fill the gaps with invented numbers.
What she has chosen instead is a life that looks ordinary from the outside and, by all accounts, is deeply valued on the inside. A home in California, a husband, children, a large extended family, and a younger sister who is one of the most famous people on earth and who still calls her for advice. It is not a life built for headlines, and it is not meant to be. The fact that people keep searching for her name says less about her than it does about the size of her sister’s fame, and the size of the curiosity that fame creates.
Common Confusions About Katianna Stoermer Coleman
Because Katianna Stoermer Coleman keeps such a low profile, and because so much of what is written about her comes from low-quality biography sites that copy each other, several errors and mix-ups keep appearing online. The most common ones are worth clearing up.
When was she born? Some sites give exact dates, the most repeated being 17 November 1999, with others saying 3 December 1999 or simply September 3. Those dates cannot be right. Zendaya was born on 1 September 1996 and has said repeatedly that she is the youngest of her siblings. If Katianna is her older sister, she cannot have been born in 1999. The most careful reporting says her exact birth date is not public knowledge, and researchers who have looked at family photos and the ages of her children estimate she is in her late thirties or early forties. Any site that gives a precise birthday for her is guessing, and the 1999 dates should be treated as wrong.
Who is her mother? Several biography sites list Claire Stoermer, Zendaya’s mother, as Katianna’s mother as well. That is wrong. Zendaya is the only child of Claire Stoermer and Kazembe Ajamu Coleman. Katianna comes from her father’s previous relationship, and her biological mother’s name has not been publicly identified. The confusion comes from sites that copy a family tree without checking it, and it is one of the most repeated errors about her.
How many children does she have? Reports conflict. Zendaya told Vogue in 2019 that Katianna has two daughters, Imani and Isys. A later PEOPLE profile describes her as a mother of three daughters. Neither account has been confirmed by Katianna herself, and the public record does not settle it. The two figures are given here side by side so readers can see the conflict rather than be given a false certainty.
Is she a social media star? No. Some sites call her a social media personality or a TikTok star, but she has no verified public social media presence, and no account of hers has ever been confirmed. The claim appears to come from sites inventing a career for a person who has none in public.
What is her net worth? Figures quoted online, usually around $500,000, come from no credible financial source and change from site to site. She has not publicly stated her net worth, and no figure should be quoted as fact.
Is she older or younger than Zendaya? Older. Despite some sites calling her the younger sibling, every reliable account agrees she is one of Zendaya’s five older half-siblings, and Zendaya is the youngest of the six children. The mix-up seems to come from the wrong 1999 birth date, which would make her younger than Zendaya, and it falls apart once that date is set aside.
Is there another half-sister? Some 2025 reports mention a further half-sister, Latonja Coleman, said to be 51 years old. That name has not been confirmed by major outlets such as PEOPLE or InStyle, which list five half-siblings, so it should be treated as reported, not established.

Conclusion
Katianna Stoermer Coleman is a reminder that the people behind famous names have lives of their own, and that a quiet life can be a full one. She grew up in Oakland in a big blended family, became the older sister a future superstar looked up to, and then chose a life built around her own home and children rather than around fame. Zendaya’s words about her say it best: she looked up to her big sister and realised the influence she had on her in becoming a better person.
Katianna Stoermer Coleman has never tried to turn that connection into a career, and she has never asked the public for anything. She keeps her birth date, her work and her family life private, and the honest thing to do is to respect that, and to say plainly where the record ends rather than filling it with guesswork. Her story is not one of fame, but of family, and it is worth telling on those terms. For readers who want to check the basic facts about her sister’s career and the family around her, a general reference is a good place to start.
