Who Is Kai Schreiber?

Overview

Kai Schreiber is a British-American model and actress who has walked runways for Valentino (Italian luxury fashion house) and Mugler (French fashion brand). She signed with IMG Models (global modeling agency) and made an early acting debut voicing a young wolf character. Vanity Fair (fashion and culture magazine) describes her as a transgender woman and the second child of Naomi Watts and Liev Schreiber.

The implication: Kai’s public profile is built on a mix of runway success and the normal teenage support of her famous parents.

What makes her notable

• She debuted at Paris Fashion Week for Valentino in March 2025 at age 16 (Hindustan Times).
• She has appeared on runways in New York, Milan, and Paris (People).
• Her Instagram account (@kaischreiberrr) has 38K followers and references IMG Models (People).

The pattern: Early stage, high profile, and firmly within the fashion industry’s spotlight system.

Is Kai Schreiber the Daughter of Liev Schreiber?

Parentage

Yes. People (celebrity news outlet) confirms that Kai Schreiber is the daughter of actor Liev Schreiber and actress Naomi Watts. The couple, who were together from 2005 to 2016, have two children: older son Sasha (born July 2007) and Kai (born December 2008). E! News (entertainment news) reports that both parents have been publicly supportive of Kai as their trans daughter.

Like other celebrity offspring navigating public life, Kai’s trajectory parallels figures such as Sunday Rose Kidman-Urban, whose biography also mirrors the dynamics of famous-parent visibility.

Are Sasha and Kai Boys?

Sasha Schreiber

People identifies Sasha Schreiber as Kai’s older brother. Sasha is described in media as a boy.

Kai’s gender identity

Kai Schreiber is a girl. Vanity Fair and E! News refer to her as a transgender woman and daughter. The answer to the search query “Are Sasha and Kai boys?” is no: Sasha is identified as a boy, Kai is identified as a girl.

The catch: Public understanding often lags behind the family’s own statements, leading to repeated clarification queries.

Did Naomi Watts Give Birth to Two Sons?

Sex assigned at birth

Naomi Watts and Liev Schreiber have two children. People notes that both children were assigned male at birth. However, Kai now identifies as female, and the family publicly supports her identity.

Current identity

Referring to Kai as a “son” is inconsistent with her current identity and with the family’s statements. E! News headlines read: “How Naomi Watts and Liev Schreiber Support Trans Daughter Kai.”

How Old Is Kai Schreiber?

Birth date

Kai Schreiber was born on December 13, 2008 (People).

Age in current coverage

Kai is 17 as of 2026. People described her as 16 during her 2025 Valentino debut, and E! News continues to use consistent age references.

Why this matters: Age discrepancies in search results stem from old articles written before her birthday, not from conflicting birth records.
