The Call Me By Your Name actor, 27, and Jenner, 25, were seen in the VIP section at Beyoncé’s third and final Renaissance tour stop in Los Angeles, which also marked the singer’s birthday.
In a clip that has been widely shared on social media, the Oscar-nominated star is seen chatting to the make-up mogul in a raised area at the SoFi Stadium in Inglewood, while appearing to smoke a cigarette.
Chalamet, who donned a black jacket by Alexander McQueen in the footage, is then seen very casually moving his arm around her as they chat and her sister, Kendall Jenner, joins them.

They weren’t the only big names at the gig, which saw Diana Ross serenade Beyoncé on stage, with Adele, Justin Bieber and his wife Hailey, Zendaya, Tom Holland, Kim Kardashian, and Khloe Kardashian, also in attendance.
Jenner and Chalamet were first romantically linked in April via celebrity gossip account DeuxMoi, which suggested they have been quietly dating since January after meeting at the Jean-Paul Gaultier fashion show.
Entertainment Tonight then cited an unnamed “source” who claimed that the two were enjoying spending time with one another, but were “keeping things casual”.
In the wake of the report, Jenner’s blacked-out Range Rover was then seen arriving at the home of Chalametfurther fuelling the speculation.
Chalamet snapped up the $11 million Beverley Hills property last year. It is about an hour away from Jenner’s $36.5 million pad in Holmby Hills estate.
While Jenner’s car was spotted at the Dune star’s house, their joint appearance at Beyoncé’s tour marks the first time they’ve actually been seen together.
Jenner is reported to have split from Travis Scott, 31, at the end of 2022. The couple had been dating on and off since 2017 – and have two children together, Stormi, five, and Aire, one.
While Chalamet has previously been linked with Lily-Rose Depp and Eiza González, and briefly dated Madonna’s daughter Lourdes Leon while they both attended LaGuardia High School in New York.
