Kylie Jenner and Timothée Chalamet are done hiding their relationship. The couple was first spotted making out at Beyoncé’s concert on September 4 and then again while watching the men’s singles finals at the US Open on Sunday. Photographers captured both PDA moments.

A source also recently spoke to People about Kylie and Timothée private dynamic. No, they are not a super serious couple yet, but they have been together for half a year, and they really like each other.

Their relationship is “fun and uncomplicated” for Kylie, People’s source said. “They have been seeing each other for six months now. He makes Kylie happy. He has his own life and understands that Kylie needs to prioritize her kids.” Kylie has two children, five-year-old Stormi and one-year-old Aire, with ex-boyfriend Travis Scott.

“He is charming, very loving, and protective of Kylie,” the source continued. “She likes that he is a private guy.”

Kylie and Timothée were first romantically linked back in April, though a video came out of them allegedly meeting for the first time at Jean Paul Gaultier’s Paris fashion week show in January.

A source told Entertainment Tonight in April that Kylie's sister, Kendall, may have connected them. “Timothée is also friends with Kendall, so it’s been easy for Kylie to integrate him into her life,” the source said.

Before Kylie and Timothée went public with their romance at Beyoncé’s concert, a source described their dynamic as still pretty casual to Entertainment Tonight on August 16.

“Kylie and Timothée are still seeing each other when they can,” the source said. “Kylie’s busy with work and traveling a lot, but they make time for each other when it works and both like each other. They’re keeping things low key and chill for now, but get along great and have fun together.”
