The TV personality supported the actor following his return to “Saturday Night Live” as a host over the weekend
The Dune star, 27, hosted the iconic show’s fourth episode in its 49th season alongside the indie trio boygenius as the musical guest. Afterward, he was joined by Jenner, 26, to celebrate his SNL gig at an afterparty in New York City.
The Kylie Skin founder was photographed in an elegant all-black look as she arrived for the post-show bash, wearing a chic off-the-shoulder top, tight black pants and black heels, which she teamed with sunglasses and a small black purse.
While The Kardashians star arrived separately to Chalamet, the actor was also pictured as he stepped into the bash wearing a particularly colorful outfit.
A smiling Chalamet teamed a blue and red hooded sweater with a purple jacket that featured a furry lining. Dark grey jeans, black and white sneakers and a black baseball cap completed his casual, yet stylish look.
This is the second time the 27-year-old Oscar-nominated actor has hosted the show since his first gig in December 2020. Chalamet opened the evening with a monologue that poked fun at stars returning to work following the end of the SAG/AFTRA strikes and saw him singing and rapping.
He also participated in a number of fun skits where he played the likes of the Man on The Moon, a muscular gym employee and a rapper. The Dune actor was joined on stage by Alec Baldwin, who made a surprise cameo.
While the Kylie Cosmetics founder did not appear to have joined Chalamet in Studio 8H, she was by his side for the following afterparty.
Jenner and the Wonka actor — first linked in early 2023 — also appeared to have been joined at post-show bash by several other stars, as Sophie Turner and Dakota Johnson were also photographed arriving at the same location.
The pair’s appearance at the comedy-sketch show’s afterparty is the latest in a string of star-studded romances to grace the show and its afterparties, following Bad Bunny and Kendall Jenner, Pete Davidson and Madelyn Cline and Travis Kelce and Taylor Swift’s.
The reality star's presence at the post-SNL bash on Saturday comes just over a week after she sat with Chalamet at the same table during the 2023 WSJ. Magazine Awards in New York City.
Jenner was honored at the awards as the magazine’s brand innovator of the year for her new clothing line, Khy. The Beautiful Boy star — who has been romantically linked in the past to Lourdes Leon, Lily-Rose Depp and Eiza González — was also there to present the director Martin Scorsese with the film innovator of the year honor.
Designer Haider Ackermann jokingly mentioned Jenner’s “very attractive lover” while he presented the beauty mogul’s award, as the Kylie Skin founder and Chalamet looked on.
Just a few moments later, Jenner thanked the magazine for the honor. "I've always loved beauty and fashion and to be recognized for the success of my brands I built and my new Khy that launched today," she said. "It's so special to me."
Though the pair haven't publicly addressed their romance just yet, Jenner did subtly hint at the connection in a recent WSJ. Magazine interview.
When asked during the interview if she's a fan of Dune, the 2021 movie starring Chalamet, Jenner said, "I do love that movie."
In a video obtained by TMZ, the pair were seen kissing on multiple occasions as they enjoyed the concert together.
