Knox Jolie-Pitt, the 17-year-old son of Hollywood stars Angelina Jolie and Brad Pitt, is gaining attention among Thai fans for his growing passion for Muay Thai after recently being spotted training seriously at a gym in Los Angeles.
Photos circulating online showed Knox training in Muay Thai shorts featuring the word “Rajadamnern” in Thai script, referencing Rajadamnern Stadium, one of the most historic and respected venues in the sport. Thai social media users quickly praised the teenager’s apparent dedication to Thailand’s national martial art.
According to entertainment reports and paparazzi photos from the past year, Knox has been training consistently in Muay Thai and appears to take the sport seriously. Images from recent sessions showed him stretching, lifting weights, sparring with coaches and training partners, and even continuing after suffering a nosebleed during practice.
His interest in the sport became widely noticed in July 2025 when he celebrated his 17th birthday by competing in an IKF Point Muay Thai Technical competition in Los Angeles. Videos from the event showed Knox exchanging punches and kicks with an opponent before eventually winning a medal. His mother Angelina Jolie and twin sister Vivienne were reportedly present to support him from the crowd.
Knox was also photographed wearing Muay Thai gear branded by Thai companies, including Tuff shorts commonly associated with the sport’s international training community.
In 2025, Knox reportedly travelled to Thailand, where he attended fights at Rajadamnern Stadium and trained at a Muay Thai camp. His visit drew additional interest among Thai fans, many of whom welcomed the growing international appreciation for the sport.
Often referred to as “the art of eight limbs,” Muay Thai is one of Thailand’s most important cultural exports and a globally recognised combat sport. Unlike Western boxing, Muay Thai incorporates punches, elbows, knees and kicks, with fighters using nearly every part of the body both offensively and defensively.
The sport originated centuries ago as a battlefield fighting technique before evolving into a professional combat sport deeply tied to Thai culture and identity. Today, Muay Thai is practised worldwide, attracting professional fighters, fitness enthusiasts and celebrities alike.
Rajadamnern Stadium, founded in 1945, is widely regarded as one of the birthplaces of modern professional Muay Thai and remains among the sport’s most prestigious arenas alongside Lumpinee Boxing Stadium.
