Katianna Stoermer Coleman, also known as Kizzi, is Zendaya’s older paternal half-sister. They share their father, Kazembe Ajamu Coleman. However, Claire Stoermer is Zendaya’s mother, rather than their shared biological mother. Public reporting identifies Katianna primarily through her connection to the actress.
Readers often search for her age, husband, children, and net worth. Yet the available evidence supports a much narrower biography than many online profiles suggest. Her family connection has reliable coverage; precise financial figures and detailed career claims do not have comparable support.

Seventeen’s profile of Zendaya’s siblings identifies Katianna by name and connects her with the nickname Kizzi. However, a published name should not automatically count as proof of a person’s complete legal name.
Her Connection to Zendaya’s Family
Katianna and Zendaya are half-sisters because they share one biological parent. Therefore, “stepsister” does not accurately describe their relationship.
Family profiles also name Annabella, Kaylee, Austin, and Julien among Zendaya’s older siblings. These names help readers understand Katianna’s place in the family without confusing her with another relative.
However, shared family membership does not establish identical childhood experiences. It also does not confirm that every sibling has the same mother. A careful biography should avoid filling those gaps with assumptions.

What Katianna Shared About Their Childhood
One valuable source is Vogue’s May 2019 Zendaya profile. Writer Maya Singer spoke directly with Kizzi, who recalled after-school snacks from their grandmother and a childhood where family members helped one another.
Kizzi also discussed Oakland’s influence and Zendaya’s awareness of differences between the schools where their parents worked. These comments offer a firsthand family perspective. However, they do not establish Katianna’s birthplace, school history, or qualifications.
That distinction matters because a relative’s interview can confirm particular memories without supporting an entire life story.

Is Katianna Married, and Does She Have Children?
Published coverage describes Katianna as married and a mother. However, sources differ in how many children they mention.
Seventeen’s June 2024 profile describes her husband and two daughters. Meanwhile, PEOPLE’s August 2026 family feature reports that Kizzi and her husband have three daughters. The later account supplies a different total, but it does not explain the difference.
Therefore, the clearest wording is that Katianna has children, with PEOPLE reporting three daughters in its later coverage. Neither account justifies guessing her husband’s identity or adding details about the children’s private lives.
Older family reporting also should not serve as proof of her present address or daily routine.
What Is Katianna Stoermer Coleman’s Age?
The reliable sources reviewed do not establish Katianna’s exact birthday or birth year. Consequently, this profile does not assign her a numerical age.
Being Zendaya’s older sister establishes their relative ages. However, it does not provide enough information to calculate Katianna’s birth date. Likewise, photographs and estimates of someone’s appearance cannot replace a documented date.
Readers should approach precise ages cautiously when a biography provides no original source for them.
Her Career, Education, and Net Worth
No sufficiently reliable source reviewed establishes Katianna’s occupation, employer, educational qualifications, or personal wealth.
This does not mean she has no career. Instead, it means the available reporting does not support a detailed professional biography. Claims that she works in entertainment, manages Zendaya, or owns particular businesses need independent evidence.
The same standard applies to Katianna Stoermer Coleman’s net worth. Zendaya’s earnings cannot establish her sister’s assets, income, or debts. Therefore, assigning Katianna a dollar amount would create an estimate without a sound factual basis.
Our profile of Samantha Char Seger also explains why a famous relative’s wealth does not establish someone’s personal net worth.
What Zendaya’s Comments Do—and Do Not—Confirm
Zendaya has spoken warmly about an older sister’s influence. However, the frequently repeated 2015 statement refers to her “big sister” without naming Katianna in the quoted passage. Although later profiles place that remark beside Katianna’s name, the wording alone does not identify her.
This distinction also applies to family photographs and online accounts. An image caption or familiar surname does not independently verify someone’s identity.
For readers, the strongest profile separates named, attributable information from assumptions. Katianna’s documented family connection already answers the main question without invented personality traits, career achievements, or financial figures.
