Angelina Jolie’s 18-year-old son Knox shows off a daring new red hair

Cherry bomb.

Angelina Jolie’s son Knox debuted a vibrant dark red hair color on Monday as he was photographed leaving a Muay Thai class in Los Angeles.

The 18-year-old’s punky ‘do was cropped close on the sides and left long and choppy up top.

He was snapped with bleached blond hair as recently as Aug. 5, putting the crimson dye job sometime within the past week.

Knox has been treating his head like a mood ring all year, kicking off 2026 with platinum strands and opting for fiery orange in the spring.

Cotton candy pink spikes came last November, debuted on a grocery run in Los Feliz. The pastel pixie drew comparisons to his mother’s hot pink bob from the 1998 film “Playing by Heart.”

The chameleonic tendency runs in the family. Angelina Jolie spent the late ’90s proving she could pull off everything from a shaved head to a spiky bleached pixie to the choppy platinum bob she wore in “Girl, Interrupted.”

She showed up at the 2000 Golden Globes with a blueish-gray crop, then collected her Oscar that March with waist-length jet-black hair.

Knox, who turned 18 on July 12, is the second youngest of Jolie and Brad Pitt’s six children, arriving minutes before twin sister Vivienne.

The “Mr. & Mrs. Smith” co-stars split in 2016 and spent more than eight years in legal proceedings before finalizing their divorce in December 2024.

All six kids have sided with their mother, with multiple legally dropping the last name Pitt, while the actor, 62, has maintained little to no contact with them since.

As for Knox, Page Six exclusively reported in June that his Fusion Academy diploma listed him as “Knox Jolie.”

A source told us the accomplished fighter celebrated his graduation alongside his mom, 51, older siblings Pax and Zahara, and Vivienne — then spent the night in the fighting ring at a Downtown Los Angeles club.

“Angie hasn’t been fighting and isn’t angry. She just wants everyone to heal,” a source close to the “Maleficent” star exclusively told Page Six last month.
