Kris Jenner has officially given her endorsement to her daughter Kylie Jenner’s relationship with actor Timothée Chalamet — and she did it in style. On Monday, December 8, the 70-year-old Kardashian-Jenner matriarch showcased her support by wearing merchandise from Chalamet’s highly anticipated upcoming film, Marty Supreme, which hits theaters on Christmas Day.

Kris Jenner’s Stylish Show of Support

Kris shared a photo to her Instagram Stories, standing in front of a beautifully decorated Christmas tree while sporting a striking blue Marty Supreme bomber jacket over a festive red dress. With her arms extended in a celebratory gesture, Kris added a caption reading, “MARTY SUPREME Christmas Day!!!!!!” signaling both excitement for the film and her approval of Kylie and Timothée’s relationship.

The jacket, a key piece in Chalamet’s promotional wardrobe for the Josh Safdie-directed film, has already been seen on Kylie Jenner during an outing to the Yankees-Jays game on October 8, 2025. Chalamet himself wore it in an Instagram promotional video for the movie back on October 7, and it even made an appearance on Tom Brady in a post shared by Chalamet in November.

Marty Supreme follows Chalamet’s character, Marty Mauser, “a young man with a dream no one respects, [who] goes to hell and back in pursuit of greatness,” according to A24. Fans of the actor can expect the film to showcase his signature intensity, as well as plenty of style inspiration courtesy of the Marty Supreme wardrobe line.

Kris’s fashion-forward endorsement also echoes the ongoing cultural influence of the Jenner-Kardashian family, as she effortlessly combines family pride with Hollywood hype. The move has already sparked social media buzz, with fans praising her creative way of showing support.
