Over the past weeks, Knox has been photographed practicing the form of martial art, including on his birthday. Paparazzi spotted him training at one of his classes, showing off his ripped thighs that suggest Knox takes his workout seriously and rarely skips out on training. 

He wore some Tuff shorts with a green band and different prints on them, pairing them with a cream colored t-shirt that read "New York Sparring Society," which features a colorful design of a green helmet and a pink boxing glove. 

Knox stretched and lifted weights, and concluded his training session with a sparring match, with him spotted grappling with his coach as he wore some protective knee pads and gloves. He had a wad of paper on his nose, containing his nosebleed.

Knox's gold medal in Muay Thai

Muay Thai is a combat sport from Thailand, with people using all of their limbs, including their fists, elbows, knees, and shins, to fight and defend themselves. 

Knox celebrated his 17th birthday on July 12, which he shares with his twin Vivienne. That day, he was photographed grabbing some groceries with his mom, and the following day he participated in the Born to Win Combat Sport competition in Los Angeles.

He was supported by Jolie and Vivienne, who cheered him on in the stands. Knox ended up winning the match, celebrating the win with some medals on social media. 

According to new reports, Brad Pitt appears to want to mend things with his children, with a source telling The Daily Mail that he was "desperate" to contact his children ahead of their birthdays. 

Per the source, Pitt wanted to "make amends" even though he knew that the chance to reunite was “remote to say the least." 

Knox appears to be the only one of his kids to retain his father's surname. Last year, Vivienne dropped her father's surname according to a 2024 Playbill from the show "The Outsiders," which she worked on alongside her mother.
