AceShowbiz - Kylie Jenner proves that she is such a supportive girlfriend for Timothee Chalamet. "The Kardashians" star was photographed attending a "Saturday Night Live" after-party following the actor's hosting gig on November 11.

The 26-year-old makeup mogul and the "Dune" star arrived separately at the bash, which took place in New York City. The mom of two went all black from head to toe for the event. Her beau, in the meantime, opted to go with a colorful jacket that he paired with gray jeans, sneakers and a black baseball cap.

Before Timothee did his duty on the sketch comedy/variety show, Kylie's mom Kris Jenner showed support to him on social media. Taking to Instagram Story, the momager unleashed a photo of the "Little Women" star, cast member Bowen Yang and musical guest boygenius. "Tune in to SNL tonight!" the 68-year-old penned in the accompanying message.

Timothee and Kylie sparked dating rumors in April and decided to go public with their romance in September. While they have yet to publicly address their romance, the pair allegedly had been enjoying a "fun and uncomplicated" relationship.

"They have been seeing each other for six months now. He makes Kylie happy," an insider shared with PEOPLE at the time. "He has his own life and understands that Kylie needs to prioritize her kids. He is charming, very loving and protective of Kylie. She likes that he is a private guy."

Earlier this month, the lovebirds packed on PDAs at the WSJ Magazine 2023 Innovator Awards. A photo surfacing online showed the Khy founder and the "Wonka" leading man standing next to each other while having a conversation with a fellow attendee inside the Museum of Modern Art. While it seemed like a casual scene, it should be noted that the couple had their fingers intertwined affectionately.
