In the midst of a family split between the former Hollywood power couple Angelina Jolie and Brad Pitttheir youngest son, Knox, appears to be following in the footsteps of his five siblings, officially dropping the “Pitt” from his last name.According to Page Six, Knox, who turned 18 on July 12, used the name ‘Knox Jolie’ on her high school diploma after graduating from Fusion Academy in Los Angeles earlier this month. The viral video of the graduation ceremony also tagged the child star as “Knox Jolie”.It comes just days after Knox’s sister, Zahara, filed paperwork to change her name from Zahara Jolie-Pitt to “Zahara Jolie.” The trend continued last month when older brother Maddox also filed court papers seeking to drop “Pitt” from the last name, citing “personal reasons.” However, according to reports, he went by the name ‘Maddox Jolie’ professionally long before he embarked on the legal path.Knox’s brother Pax also reportedly goes by the name ‘Jolie’ in his professional life, and Vivienne is also listed as ‘Vivienne Jolie’ in the credits of her broadway production.In 2024, Shiloh made waves when she petitioned a Los Angeles court to legally remove the last name “Pitt” shortly after her 18th birthday.According to Page Six, a source told the outlet that Angelina is “pretty happy with herself for the success of her long, intense and deliberate effort to distance her children from their father.”“It’s so sad for the whole family that she would use the same weapon of name change over and over again for no other purpose than to hurt her father,” the insider continued. “This was his goal and he achieved it.”However, another source said, “Angelina has been involved in family therapy with Brad and the kids after years of therapy to try and heal everyone involved after the events that led to her filing for divorce.”The source added: “The kids are adults now and they make their own decisions, which deserve respect. If they choose to walk away from him, it comes from that pain and hurt. It’s really terrible that he tried to paint himself as a victim. When are people going to start asking the kids real questions about what happened?”Brad finalized his divorce from Angelina in December 2024, after the actress filed for divorce in September 2016 following their decade-long romance.
