Brad Pitt and Angelina Jolie’s youngest son Knox Jolie-Pitt unveiled a shocking new look over Memorial Day weekend, stepping out in Los Angeles with a bright orange hairstyle after finishing a Muay Thai class.

The 17-year-old was snapped after training, his striking new hair color adding to the eccentric colors of his workout fit.

The teen’s yellow athletic shorts and lavender hoodie left cuts and bruises still visible — a testament to his years of dedication to the combat sport.

Knox has occasionally been spotted at competitions alongside mom Angelina Jolie and twin sister Vivienne, who have previously shown support ringside during matches and events.

While Knox has largely stayed out of the public eye compared to some of his famous siblings, the teen’s vibrant new hair color certainly draws attention.

Knox was spotted multiple times over the holiday weekend, sporting a gray t-shirt paired with bold tiger-print shorts and the pop of orange on top of his head after another workout.

Knox is also one of the few Jolie-Pitt children who has publicly continued using Pitt in his surname, though it remains unclear how close he currently is with his Oscar-winning father.

He and his twin sister Vivienne were born in 2008 and are the youngest of Jolie and Pitt’s six children.
