Kylie Jenner and Timothée Chalamet's Relationship Is 'Very Easy': ‘He’s Part of the Family Now’ (Exclusive Source)

Kylie Jenner and Timothée Chalamet are enjoying their romance.

Amid the holiday season, Jenner and Chalamet’s relationship is still going strong. A year and a half after they started dating, Jenner, 27, is now integrating the Wonka actor, 29, into her home life, a source tells PEOPLE.

"They had an early Christmas celebration together before Kylie spent Christmas Day with her family,” the source says. “It took Kylie a long time to introduce him to her kids. He's part of the family now though. Her kids know him as a 'friend.' ”

The source adds: “Her relationship with him is great and very easy. He's super supportive of her priorities and he works around her schedule a lot. They are both committed to making it work."

Earlier this month, Jenner and Chalamet made a rare public appearance together at the A Complete Unknown afterparty in Los Angeles. Photos captured the couple cozying up to one another as Chalamet celebrated the launch of his latest movie.

Jenner skipped the red carpet, but she and the Dune star were “pretty affectionate with each other” at the afterparty, according to an insider. Chalamet, who received his fourth Golden Globe nomination for his portrayal of Bob Dylan in the film, settled into his roped-off section of the party with his girlfriend as she sat in his lap and gave him a quick kiss.

The pair don’t often step out in public together — before the December premiere party, they were last seen on a low-key dinner date at Little Charli in the West Village in New York City in October. A source later told PEOPLE that they were "very cuddly and very cute" and "looked very much in love" during the date.

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

In the past, Jenner has made sure to show up to support Chalamet’s projects. In December 2023, she attended the L.A. and London premieres of Wonka, although she kept it low-key.

In August, The Kardashians star even told British Vogue that she had been able to fly under the radar during her NYC visits (at the time, Chalamet was there filming Marty Supreme), and a source told PEOPLE they were "able to figure out a good balance between working and spending quality time together."

"I haven't had one person notice me. I've been really able to get around," Jenner revealed to the magazine. She even admitted to frequently "walking the High Line" without getting recognized.
