Timothée Chalamet might be test-driving a new look. The actor, 29, joined girlfriend Kylie Jenner in St. Tropez Monday, where the makeup mogul has been partying with sister Kendall and friends for the past few days. And while the reality stars have been having a blast and making a splash with their fashion, Chalamet stole the show with his choice of accessories: a Nike baseball cap secured with a green bandana knotted beneath his chin, babushka-style. Eagle-eyed fans noticed that beneath both, the nape of Chalamet’s neck appeared to be closely shaven. “OMG BUZZ CUT!!??,” one fan frantically tweeted. “the italian grandmother chic is sending me 😭😭,” another wrote. “That’s disappointing. I guess we’re stuck with that for DUNE 3,” a third replied. It’s been reported that “Dune: Messiah,” part three of Denis Villeneuve’s Timmy-fronted franchise, will begin filming in Budapest this week, with the star shedding his signature curls for the role. He’s also ditched his polarizing “Marty Supreme” mustache ahead of that film’s theatrical release on Christmas Day. It’s unclear what Chalamet’s character, Paul Atreides, will look like in the latest “Dune” movie, which is set one decade after “Dune: Part Two.” Chalamet paired his cap-and-headscarf combo with a Nigerian soccer jersey and a $40,000 diamond Cartier pendant necklace, while Jenner showed off her curves in a vintage Jean Paul Gaultier cone-bra minidress. Kylie and Kendall have been living it up in Europe lately, following their trip to Venice for Jeff Bezos and Lauren Sánchez’s wedding. The sisters took a dip in their clothes while partying at the exclusive Loulou’s beach club and sipped cocktails while showing off their designer bags. Chalamet and Jenner have been dating for more than two years, and made their red carpet debut as a couple at the David di Donatello Awards in Rome in May. Jenner recently took their relationship to the next level by following Chalamet on Instagram. He has yet to return the gesture, and currently follows no one on his account.
