Timotheé Chalamet and Kylie Jenner Showed Off Plenty of PDA on Rare Public Date Night at“ A Complete Unknown” Afterparty

Kylie Jenner was on hand to celebrate with Timothée Chalamet at the premiere of his latest major movie.

On Tuesday, Dec. 10, Jenner, 27, joined Chalamet, 28, at the afterparty following the L.A. premiere of A Complete Unknown at the Dolby Theatre, and the couple were not afraid to show off some rare PDA.

Though Kylie did not walk the red carpet at the premiere, she and her mom Kris Jenner arrived at the afterparty, and Kylie and Chalamet were "pretty affectionate with each other" as guests began trickling in.

As the actor — who just earned his fourth Golden Globe nomination for his portrayal of Bob Dylan in the film — settled into his roped-off section of the party, Kylie sat in his lap with her arm around his shoulders and they shared a quick kiss.

Throughout the night, the couple mingled with Chalamet's costars and other guests and were smiling and happy together. Though they held off on the PDA as the party filled up, Kylie often touched her beau during conversations — and was spotted playing with the hem of his jacket a few times.

At the end of the night, they departed the party together, hand-in-hand.

The outing in L.A. was a rarity given how long the pair have been romantically linked — since April 2023 — and how infrequently they step out together publicly.

Kylie has been supportive of her beau's projects in the past, though, and she similarly attended the L.A. premiere of Wonka under the radar last December with her mom. She had also attended the London premiere a week prior, sources told PEOPLE at the time.

They were last seen together in New York City in October as they had a low-key dinner date at Little Charli in the West Village. A source later told PEOPLE that they were "very cuddly and very cute" and "looked very much in love" during the date, which echoed what another insider had shared earlier that month.

"Everyone loves them together," a source close to Kylie said. "He's close with her family and she's close with his family. It's very serious, but also a fun relationship."

At the time, Chalamet was filming Marty Supreme in New York City while Kylie was in L.A., and the source said they've "really been able to figure out a good balance between working and spending quality time together."

Kylie also recently revealed that she's in New York City quite a lot — and she's able to fly under the radar in the big city.

"I haven't had one person notice me. I've been really able to get around," she told British Vogue in August. She even admitted to frequently "walking the High Line" without getting recognized.
