What gender is Kai?
Kai Schreiber’s pronouns and identity
- Kai Schreiber is a transgender female. She uses she/her pronouns, as confirmed by her father Liev Schreiber in a May 2025 interview with Variety.
- Liev Schreiber told Variety that Kai asked for a change in pronouns, which he described as the key moment in the family’s understanding of her identity.
- Vanity Fair described Kai as a transgender woman born in New York City in 2008 (Vanity Fair).
Public confirmation of gender
- Kai publicly identified as female during her teenage years. Her father said in Variety that Kai never explicitly told him and Naomi Watts she was transgender — instead, she asked for a change in pronouns.
- Variety reported that Liev Schreiber described Kai as having been feminine for a long time.
Kai’s gender identity is publicly acknowledged by her family and media, but the narrative is driven by parental interviews rather than a direct statement from Kai herself — a gap that reflects her age and the family’s desire for privacy.
Does Naomi Watts have two sons?
Naomi Watts’ children: Kai and Samuel
- Naomi Watts has two children: Kai (now daughter) and Alexander “Sasha” Schreiber, born in July 2007 (People).
- Both children were assigned male at birth. Kai now identifies as female, so the family includes one daughter and one son.
- People reported that Kai is the younger of Liev Schreiber and Naomi Watts’ two children.
How Kai’s transition changed the family dynamic
- Liev Schreiber and Naomi Watts split in 2016 after an 11-year relationship but remained committed co-parents (People).
- Naomi Watts has publicly supported her daughter. She marked Kai’s 16th birthday in December 2024 with an Instagram post (People).
- E! Online reported that Naomi Watts called herself a “momager” in relation to Kai’s modeling career (E! Online).
The family’s public support — from both parents and the sibling — provides a rare window into how a celebrity family navigates a child’s gender transition under media scrutiny.
How old was Kai Schreiber when she started transitioning?
Age at which Kai began social transition
- Kai Schreiber began her transition during her teenage years. The exact age of start is not publicly confirmed.
- She came out publicly around age 16 (2024/2025), according to reporting from Variety.
- Liev Schreiber told Variety that the pronoun change request was the defining moment, but did not specify when it occurred.
Medical transition timeline and privacy
- No medical or legal Tier 1 sources (e.g., hospital, court documents) have confirmed any medical transition steps.
- The family has not publicly discussed medical transition details, consistent with privacy norms for a minor.
Was Kai originally a girl?
Assigned sex at birth
- Kai Schreiber was assigned male at birth, as reported by People and Vanity Fair.
- She is a transgender woman. She has identified as female since her early teens.
Understanding transgender identity
- Kai’s identity as a transgender woman means her gender identity (female) differs from the sex she was assigned at birth.
- Her father’s comments to Variety — that Kai had been feminine for a long time — align with common narratives of transgender individuals who express their gender identity from a young age.
Without a direct statement from Kai herself, the public narrative relies on parental accounts. This is not unusual for a 16-year-old, but it means the story is filtered through adult perspectives.
What happened to Naomi’s two sons?
Kai’s gender transition
- One of Naomi Watts’ sons, Kai, transitioned to female. The family now includes a daughter (Kai) and a son (Samuel).
