Knox, 17, was spotted leaving a Muay Thai workout, one of his biggest passions. He wore an outfit made up of a pink sweatshirt with the Cinamorroll character printed on it, baggy cream colored pants, and white Nike sneakers. 

The outfit highlighted his bleached-blonde hair and dark roots, resulting in a punk, cool look that balanced the pink tones in his clothing. He was photographed climbing into his car, getting ready to go home.

Knox has been experimenting with his hair over the past months, debuting a pink hairstyle in November of last year. His new hairstyle shows off longer dyed hair, which has shed its bright hue with the passage of time.

When it comes to his interests, Knox leads a relatively private life, having no public social media profiles and avoiding interactions with the media. As he’s grown up, we’ve learned that he’s enthusiastic about his fitness, being photographed on outdoor runs across Los Angeles. His biggest passion appears to be Muay Thai, and he practices the sport consistently. Last year, on his birthday on July 17th, he celebrated it with a Muay Thai competition, enrolling in the Born to Win Combat Sport competition – IKF point Muay Thai and PBSC Point Boxing Sparring Circuit.   

He was supported by his mom and his twin sister Vivienne, with the two cheering him in the stands. Knox ended up winning the tournament, posing with his medals for the academy’s social media.

Other celebrities who are Sanrio fans

Knox isn’t the only celebrity who has a fondness for Sanrio characters. Over the years, celebrities like Paris Hilton, Dua Lipa, Snoop Dogg, and more have shared photos with Sanrio characters like Hello Kitty.

New generations of celebrity kids have embraced newer characters developed by the company, including Knox himself and North West, who has had Hello Kitty-themed parties. She’s also been photographed alongside Kuromi dolls, another Sanrio character known for her rebelliousness and girly attitude.
