Six key facts about Knox Jolie-Pitt paint a clear picture of his life so far.

Are Knox and Vivienne Twins?

Knox and his sister Vivienne are fraternal twins, born on July 12, 2008, in Nice, France, to Angelina Jolie and Brad Pitt (E! Online Canada). They are the youngest of the six Jolie-Pitt children.

What is the age difference between Knox and Vivienne?

There is no age difference — they are twins, born minutes apart. Reports consistently describe them as fraternal, not identical, meaning they share the same birthday but do not look alike (E! Online Canada).

Are Knox and Vivienne identical or fraternal twins?

Fraternal. Multiple entertainment outlets, including E! Online Canada, have reported that the twins are not identical. Vivienne has appeared with her mother at red-carpet events, while Knox has maintained a lower profile.

The contrast between their visibility underscores how even twins raised in the same environment can choose different public paths.

Does Knox Have a Relationship with Brad Pitt?

Public records and court documents suggest a strained relationship. Knox is not seen with his father Brad Pitt, and the family’s highly publicized custody battle has kept the children mostly with their mother (E! Online Canada).

Why are Knox and his siblings reportedly estranged from Brad Pitt?

The divorce filing in September 2016 marked the beginning of a long legal fight. Court documents and anonymous sources cited by People indicate that the children have had limited contact with their father since the separation.

Do any of Brad Pitt’s other children speak to him?

Reports vary. Some older children, like Maddox, have been publicly estranged, while others, like Pax, have posted critical messages on social media. The status of the relationship with Knox and Vivienne remains private (E! Online Canada).

The implication: legal estrangement often translates into personal distance, especially for the youngest children.

What Gender Does Shiloh Identify As?

Shiloh Jolie-Pitt, Knox’s older sister, identifies as female. She legally changed her name in 2025, dropping “Pitt” from her surname (People).

When did Shiloh Jolie-Pitt publicly change her name?

In May 2025, Shiloh filed a petition to legally change her name to Shiloh Jolie, removing the “Pitt” portion. The petition was granted later that year (People).

How has the family supported Shiloh’s gender identity?

Both Angelina Jolie and Brad Pitt have publicly expressed support for Shiloh’s identity. In a 2021 interview with The Guardian, Jolie said, “She’s a girl. She’s not a boy.” The family has consistently backed her choices.

What Has Knox Jolie-Pitt Done Recently?

The most newsworthy events of Knox’s life happened in a span of 12 months: high school graduation, a Muay Thai fight, and a surname change on his diploma.

When did Knox Jolie-Pitt graduate from high school?

Knox graduated from Fusion Academy in Los Angeles on June 5, 2026 (USA Today). His mother Angelina Jolie attended the ceremony, and he wore a blue cap and gown.

Did Knox Jolie-Pitt compete in a Muay Thai fight?

Yes. That same evening, Knox competed in a Muay Thai match. According to The Independent, he told the graduation crowd he would fight later that night and went on to win the bout at Total Sonic Knockout 5.

Why did Knox Jolie-Pitt drop the ‘Pitt’ from his name?

His graduation diploma read “Knox Jolie” instead of “Knox Jolie-Pitt” (SheKnows). The move mirrors Shiloh’s name change and suggests a personal preference to follow his mother’s surname.

The pattern: surname changes among the children signal a collective shift away from the father’s name.

What Was Knox Jolie-Pitt Known for as a Child?

Before the graduation and Muay Thai, Knox was known primarily as a Hollywood child: he appeared in a single film, Kung Fu Panda 3, and was photographed occasionally with his family.

What movies did Knox Jolie-Pitt appear in?

Knox voiced the character “Young Po” in the 2016 animated feature Kung Fu Panda 3 (People). His sister Vivienne also voiced a small role. Their father Brad Pitt did not appear in the film.

Did Knox Jolie-Pitt grow up in the public eye?

To a degree. As the children of two of the world’s biggest movie stars, Knox and his siblings were photographed by paparazzi frequently during their early years. However, Angelina Jolie has made a deliberate effort to keep them out of the spotlight since the divorce (E! Online Canada).

The catch: his early fame was inherited, not chosen, and his recent steps suggest a move toward autonomy.

Comparison: Knox, Vivienne, and Shiloh

Three of the youngest Jolie-Pitt children share a similar upbringing but differ in public profiles and personal choices.

The pattern: all three are moving away from the “Pitt” name, but Knox’s athletic debut sets him apart from his sisters.
