Kylie Jenner is keeping up with her boyfriend.
The Kardashians star made a surprise appearance in New York City to support Timothée Chalamet at the New York Film Festival for the premiere of his film Marty Supreme on Oct. 6, just hours after attending Paris Fashion Week.
In a video shared to the festival’s official X account, Kylie, 28, appeared backstage as director Josh Safdie made his way to the stage and announced to the crowd that they were at the film’s premiere.
For his part, Timothée, 29, appeared alongside his director and costars Tyler, The Creator, Odessa A'zion, Luke Manley and Ronald Bronstein on the carpet for the event.
Kylie’s appearance in NYC came hours after she showed some skin during Paris Fashion Week. Earlier in the day, the Kylie Cosmetics founder attended the Mui Mui Spring/Summer 2026 presentation.
During her time in the City of Lights, Kylie—who shares kids Stormi, 7, and Aire, 3, with Travis Scott—wore a sheer lace dress by the fashion house, which she accessorized with silver socks and black heels.
In an Oct. 6 photo dump, Kylie shared a series of BTS pics and selfies in her look, writing, “I love @muimui.”
Kylie is no stranger to supporting her boyfriend. In fact, after the internet recently speculated about the status of their relationship—which began in 2023—the pair quickly shut it down. Just days after celebrating her birthday, Kylie jetted to Budapest, Hungary where Timothée was filming Dune: Part Three.
While there, the couple posed with staff at a local coffee shop who posted their photo on Instagram Aug. 19 alongside a caption that read, “They were super nice and kind thank you for coming.”
And despite their coffee shop dates, red carpet appearances and dinners from coast-to-coast, Kylie has remained firm on keeping their relationship private, telling British Vogue in 2024 that their level of privacy, “feels so good."
