Angelina Jolie's son Knox channels estranged dad Brad in Fight Club... after dropping F-bomb in graduation speech

Angelina Jolie's youngest son, Knox Jolie- Pitt, might be 17, but he's proving to be a true force to reckon with.

The teenager recently celebrated his high school graduation, and hours after that, he was seen stepping into a Downtown LA club for a Muay Thai exhibition fight. During his grad speech, he shared more about the late-night match and excitedly explained to the audience that he was going to knock out his contenders.

Knox, who turned heads at the graduation ceremony with an orange-red ombre haircut, gave the crowds a heads-up about his upcoming martial arts match at the Total Sonic Knockout 5. His proud mother was in the audience at the time and captured this wonderful milestone.

She soon showed up to cheer him on as he traded his cap and gown for a pair of fighting gloves. Videos of the very impressive sparring session quickly sparked some viral comparisons to his dad's iconic performance in the 1999 cult classic Fight Club.
