Kylie Jenner and Timothée Chalamet's relationship 'very easy'

Kylie Jenner and Timothée Chalamet are reportedly doing great in their relationship.

One source has spilled the beans on their relationship dynamics, claiming that the Wonka actor, 29, is a "part of the family now" after a year and a half of dating The Kardashians star, 27.

"They had an early Christmas celebration together before Kylie spent Christmas Day with her family,” the source told People Magazine.

“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 insider added, noting Chalamet's terms with the mother of two—who shares daughter Stormi, 6, and son Aire, 2, with ex Travis Scott.

The source continued, “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. Per an insider, she and the Dune star were “pretty affectionate with each other” at the afterparty.

Before their recent public appearance, the couple was last spotted on a low-key dinner date at Little Charli in the West Village in New York City in October, which reportedly was a "very cuddly and very cute" outing and the pair "looked very much in love" during the date.

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