Kylie Jenner has her lips firmly in place! On Monday (Sept. 4), the Kylie Cosmetics entrepreneur unveiled her new lover, actor Timothée Chalamet, during Beyoncé’s Los Angeles tour stop.

Jenner and Timothée locked lips multiple times during Beyoncé’s 42nd birthday celebration on stage. Jenner is seen once with her arms around his neck. At times, they kissed as he held her from behind and vice versa.

TMZ was the first to publish an exclusive video of the kisses. According to the site, Kylie and Timothée Chalamet were in the VIP section with other celebs. Kendall and Kim Kardashian, as well as Hailey and Justin Beiber, were all present.

Jenner has not publicly reacted on the announcement of her new beau. It’s also unknown whether the couple is an official couple or how long they’ve been dating.

Rumors of a romance between them began to circulate early this year. According to TMZ, Kylie’s black Range Rover was caught in Chalamet’s Bevelery Hills driveway one day and at a taco stall the next. Meanwhile, the site apparently confirmed, via sources, that the couple was still dating early last month.

It’s still unclear how Kylie and Timothée met. However, the 27-year-old has his own Hollywood motion. Timothée Chalamet, if you’re unfamiliar, is a French-American actor.

According to IMDB, he began his cinematic career in 2014, portraying Matthew McConaughey’s kid in “Interstellar” and a high school student in “Men, Women, & Children.” Previously, the actor had been in stage plays and television dramas such as “Law & Order” and “Royal Pains.”

With the release of “Wonka” later this year, Chalamet will have another chance to wow audiences.

He has been silent about the developing romance. Travis Scott, who has two children with Kylie Jenner, has likewise been silent.
