Knox Jolie-Pitt channels dad Brad Pitt's 'Fight Club' energy in Muay Thai match - WATCH

Angelina Jolie's six kids may be distancing themselves from dad Brad Pitt, and legally dropping his last name, but that has not stopped fans from comparing the spitting resemblance between the two.

The latest video going viral online features 17-year-old Knox channelling some of his dad, Brad's 'Fight Club' energy as he stepped into the ring for a Muay Thai match. As per reports, mom Angelina Jolie and his twin sister, Vivienne, were spotted in the crowd cheering him on. The teen, who has been a professional fighter, showcased the skills he has been developing over the past few years.

Videos obtained by TMZ showed Knox landing some punches and kicks and also taking a few blows as he battled his opponent. Videos from the event had fans on the internet comparing him with his superstar dad, who took on a similar role for his turn in the cult classic 'Fight Club'.

The teen stepped into the ring on the same day as his graduation ceremony. While delivering his graduation speech, he was even seen inviting his classmates to his match to watch him "knock 'em" out.

Unlike some celebrity children, Knox has largely remained out of the spotlight over the years, making only occasional public appearances and one rare red carpet appearance with his mom, Angelina Jolie.

When not with his superstar mom, or going about his day with his siblings, Knox has been spotted regularly attending his martial arts training sessions. Videos of his fights at the gym have often made their way online through fan handles.
