Angelina Jolie cheers on son Knox at MMA fight ahead of his 17th birthday

Angelina Jolie cheered for her son, Knox Léon Jolie-Pitt, as he competed in a martial arts competition ahead of his 17th birthday.

The “Maleficent” star and Knox’s twin sister, Vivienne Jolie-Pitt, were spotted in the crowd as the athlete won the IKF Point Muay Thai Technical event on Friday, per TMZ.

Footage obtained by the outlet showed the teen throwing punches and kicks at his opponent on the mat.

Knox was later seen photographed with a gold medal around his neck.

Jolie, 50, posed for a photo with one of Knox’s coaches.

The Oscar winner kept her appearance low-key, wearing a black long-sleeved top and black pants along with sunglasses despite being indoors.

The mother-son duo later stepped out together in Los Feliz, Calif., on Saturday — which was Knox and Vivienne’s birthday — to visit the Lazy Acres magazine shop.

Jolie was also spotted giving Knox a driving lesson.

Knox, meanwhile, appeared in good spirits while outside of his Muay Thai gym in Los Angeles on Monday afternoon.

The teenager sported white shorts, a black T-shirt, white Crocs and carried a red gym bag.

He had his hands wrapped up and later put on white gloves.

Brad Pitt, meanwhile, was absent from Knox’s tournament after an insider told the Daily Mail last week that the actor was “desperate” to “make amends” with his twins.

According to the source, the “F1” star, 61, wanted to see Knox and Vivienne ahead of their birthday, though it’s unclear whether the teens accepted the invitation.

Knox has kept “Jolie-Pitt” as his last name despite Vivienne dropping Pitt from her surname in “The Outsiders” Playbill last year.

The insider noted that Pitt has a “glimmer of hope” in reconciling with Knox after the actor was “devastated” by Vivienne’s decision.

Last month, Us Weekly reported that the “Fight Club” star occasionally sees Knox and Vivienne despite having a “strained” relationship with his and Jolie’s other children — Maddox, 23, Pax, 21, Zahara, 20, and Shiloh, 19.

Pitt became estranged from several of his kids after he and Jolie called it quits in 2016 following an allegedly violent incident on a plane.
