Katianna Stoermer Coleman is Zendaya’s older half-sister, sharing the same father, Kazembe Ajamu Coleman. Known within the family as Kizzi, she is described in entertainment profiles as a married mother. Her connection to Zendaya has brought attention to her family background and the relationships that surround the actress away from work.
Some of the clearest details come from family interviews. In Vogue’s 2019 profile, Kizzi recalled their Oakland childhood, while the writer accompanied Zendaya as she collected Kizzi’s daughters from school. These accounts offer a glimpse of the sisters’ relationship through shared memories, school pickups, and everyday time with the children.

Her Reported Age and Conflicting Birth Dates
Katianna Stoermer Coleman’s exact age is difficult to establish because online biographies give inconsistent birth details. One profile lists March 11, 1994, yet later acknowledges uncertainty and disputes the 1999 birth year circulated elsewhere. Neither date is supported there by a family statement or a cited birth record.
Established family profiles describe her as Zendaya’s older sister. Zendaya was born on September 1, 1996, so a 1999 birth would conflict with that description. This comparison places Katianna at least 30 years old as of October 2026, but it establishes only a minimum. Her precise birthday and age remain unverified.
Her Oakland Background and Childhood Memories
Katianna’s memories of Oakland center on family routines and shared responsibilities. In Vogue’s 2019 profile of Zendaya, she recalled their grandmother making peanut butter and jelly sandwiches after school. She described a warm childhood in which everyone helped, including her youngest sister.
Her reflections also connected their upbringing with Oakland’s history and social awareness. Kizzi discussed the differences between the public school where Zendaya’s mother taught and the private school where their father worked. She felt those contrasts helped her younger sister recognize inequalities within the community and understand the world around her.
Her Father, Kazembe Ajamu Coleman, and Their Blended Family
Katianna Stoermer Coleman shares her father, Kazembe Ajamu Coleman, with Zendaya. Kazembe welcomed children before his relationship with Claire Stoermer, who is Zendaya’s mother. Katianna and Zendaya therefore have different mothers, making them paternal half-sisters within the wider Coleman family.
Her father previously worked as a teacher and later became Zendaya’s manager. Claire also worked in education, giving Zendaya an upbringing shaped by two educators. When their separation became public in 2016, Zendaya explained that her parents had already been apart for some time and remained friends. Their separation added another chapter to the family’s history.
Her Brothers and Sisters in the Coleman Family
Family profiles commonly name Katianna alongside her brothers, Austin and Julien, and sisters Annabella, Kaylee, and Zendaya. Julien is also known as EZ and has children of his own, including Ezenia, whom Zendaya calls Zink. These relationships connect Katianna to an extended family of siblings, nieces, and nephews.
Reporting in 2025 also identified Latonja Coleman as Kazembe’s eldest daughter from an earlier relationship. She is another paternal half-sister within the family, separate from the five children commonly discussed together in entertainment profiles. Including Latonja explains why some accounts describe Zendaya as having six older half-siblings, while others list five.
Why She Is Also Known as Kizzi
Kizzi is the family nickname used for Katianna Stoermer Coleman. ELLE identifies her by both names in its guide to Zendaya’s siblings and uses Kizzi while discussing her marriage and children. Readers researching the Coleman family will therefore encounter both versions in entertainment coverage.
The nickname also appears in Vogue’s 2019 profile of Zendaya, which includes Kizzi’s own recollections of their Oakland childhood. These references connect the name directly to the older sister discussed in ELLE’s article. Neither publication explains who coined Kizzi or how the nickname originated, so its original meaning remains undocumented.
Her Sister Zendaya’s Rise From Disney to Hollywood
Katianna’s younger sister first became widely known as Rocky Blue in Disney Channel’s Shake It Up. Zendaya later played teenage spy K.C. Cooper in K.C. Undercover. Her move into cinema included Spider-Man: Homecoming and the musical The Greatest Showman, both released in 2017.
Her portrayal of Rue Bennett in HBO’s Euphoria earned lead actress Emmy Awards in 2020 and 2022, making her the youngest performer to win that category twice. Her film career also expanded through playing Chani in Dune and Tashi Duncan, a former tennis prodigy turned coach, in the 2024 drama Challengers.
Zendaya’s Comments About Her Older Sister’s Influence
In a November 2015 interview with TIME, Zendaya said her personal role models had changed as she grew older. She mentioned admiring Michael Jackson and Beyoncé, then explained how strongly she looked up to her parents and older sister. She credited her sister with influencing her character and helping her become a better person.
ELLE later included these comments in its section about Katianna, known as Kizzi. TIME’s original interview did not identify the sister by name. Zendaya also explained that growing older had deepened her appreciation for belonging to a large, grounded family.
Her Marriage and What Is Known About Her Husband
Katianna Stoermer Coleman is described as married in profiles of Zendaya’s family. Her husband is mentioned in connection with their daughters, although the coverage does not give his name, occupation, or wedding date. Details about how the couple met and the early years of their marriage are also absent from these accounts.
Their family has remained connected to Zendaya as her acting career developed. PEOPLE reports that she babysat Kizzi’s daughters during her Disney years, placing her sister’s household within that period of her life. These published memories highlight her role as an aunt alongside her work on television.
Her Daughters and Zendaya’s Role as an Aunt
PEOPLE describes Katianna Stoermer Coleman as a mother of three daughters. Two of them, Imani and Isys, featured in Vogue’s 2019 profile of Zendaya. Their conversations with their aunt included schoolwork, K-pop, and Harry Potter, offering a glimpse of the familiarity and humor within the family.
Zendaya has affectionately described her nieces and nephews as “borrowed children,” joking about enjoying their company before returning them to their parents. She has also explained that thinking about them influences how she responds to public criticism. Her comments combine playful affection with a desire to show them how to speak up confidently and respectfully.
School Pickups and Family Time in Vogue’s 2019 Profile
Vogue’s June 2019 cover profile followed Zendaya on a day off as she collected Kizzi’s daughters from school. She joked about being an “Uber driver” and set out in a rented SUV with her dog, Noon. At Imani’s school, she playfully honked the horn to embarrass her niece.
After collecting Isys, the group returned to Zendaya’s home, where conversation turned to schoolwork and dinner. Plans for roasted vegetables gave way to Thai takeout. The visit captured the practical side of her role as an aunt, from driving and discussing homework to sharing a relaxed meal with her nieces.
Family Photos and Her Social Media Presence
Family photos occasionally bring Katianna Stoermer Coleman into Zendaya’s public story. ELLE’s 2024 sibling profile includes Instagram posts in its Kizzi section and mentions a prom photograph with her brother Julien, known as EZ. The picture offers a glimpse of their family history beyond Zendaya’s entertainment career.
ELLE also reported that Kizzi did not have public social media accounts. The article does not identify a personal Instagram handle for her. Her presence in that coverage comes through family photographs and relatives’ posts, so being pictured online does not establish that she runs the account sharing the image.
Career Information and Published Net Worth Estimates
Katianna Stoermer Coleman’s family profiles do not identify an employer, job title, or salary. One online biography assigns her the role of Rocky Blue in Shake It Up, although Disney’s official credits name Zendaya. That error undermines the biography’s claims about Katianna’s entertainment career.
A June 2023 GistFest profile repeats wealth estimates of $500,000 and $5 million, explicitly calling them unverified. The article provides no asset, debt, or income calculation to support either amount. These remain published website estimates without a documented financial basis for establishing her personal net worth.
