Timothée Chalamet is facing criticism after being filmed smoking at Beyoncé's Renaissance tour in Los Angeles

• Timothée Chalamet went to Beyoncé's third and final Renaissance show in Los Angeles on Monday.
• A video posted on social media shows him smoking what appears to be a cigarette inside the venue.

Timothée Chalamet surprised fans on Monday when he was spotted at Beyoncé's final Los Angeles stop on her Renaissance World Tour, joining Kylie Jenner in the VIP section at SoFi Stadium in Inglewood, California.

The pair have been rumored to be dating since April, though they haven't been seen in public as a couple until now.

Video footage posted on social media shows Chalamet and Jenner laughing and talking. But the clip also shows Chalamet smoking what appears to be a cigarette, leading to criticism on X, the platform formerly known as Twitter.

One user wrote: "I fear I have entered my Timothée Chalamet ick era because WHY ARE YOU SMOKING IN AN ENCLOSED SPACE."

Per SoFi Stadium's website, it appears that smoking is prohibited inside the venue.

"The Venues are drug-free and smoke-free environments. The use of drugs (including marijuana), other illegal substances and/or smoking (including vaporizers, e-cigarettes and smokeless tobacco) is strictly prohibited," reads the venue's guest code of conduct policy.

Representatives for Chalamet and SoFi Stadium didn't immediately respond to Insider's requests for comment.

Another X user wrote: "Timothee chalamet smoking a cig at Beyoncé's birthday show for her to inhale does not sit right with me."

"timothée babe ily, but why are you smoking inside the stadium and literally in front of kylie," wrote another person.

Monday's Beyoncé concert, which took place on the singer's 42nd birthday, was attended by major A-list names, including Chalamet and Jenner.

Jenner's siblings Kim and Khloé Kardashian were also in the crowd with Kim's daughter, North West, and Kourtney Kardashian's daughter, Penelope Disick.

Other celebrities in attendance reportedly included Zendaya and Tom Holland, Justin and Hailey Bieber, Adele, Lizzo, Katy Perry, and Kate Hudson.

Diana Ross also surprised Beyoncé onstage with a rendition of "Happy Birthday."
