Brody Jenner came to his sister Kylie Jenner’s defense as he stood up for her boyfriend, Timothée Chalamet, after reports of his alleged romance with former adult entertainer Sarah Tena surfaced.

“Oh god. Just leave the happy couple alone. People have lives before they meet their person,” Brody wrote under a Page Six Instagram post shared on Monday.

“This girl is clearly doing this for attention, and everyone can see right through it.”

Tena made headlines earlier this week after she came forward alleging to have engaged in a years-long romance with the three-time Oscar nominee.

The 32-year-old told the Daily Mail that she and Chalamet’s fling began in 2020 after she saw his performance in “The King” and then slid into his DMs on Instagram.

“I thought, ‘Oh, who’s this actor,’ because I’d never seen him before, so I looked him up on Instagram,” she recalled. “I was like, ‘Oh, this guy is handsome.’ Then a couple weeks go by, and he posts a story.”

Three months later, the actor responded back by liking her message. They allegedly eventually decided to meet up for a date at his pal’s beachfront home in Santa Monica, Calif., where she claimed they instantly “clicked” over wine and a shared love for film.

Tena claimed they began seeing each other almost every other month. Eventually, she said she declared her love for the actor in June 2022.

“I was in love with Timothée, yeah. I didn’t say those exact words to him. I had said, ‘I have feelings for you,’ and pretty much expressed I want to continue. I let him know that I wanted it to be more consistent … I wanted it to be where we made more time for one another. New York kind of sealed that for me,” she told the outlet.

But things reportedly fizzled out quickly around January 2023 after the adult actress sent the actor a “happy birthday” message which he simply “hearted.”

Less than three weeks later, Chalamet, 30, was seen spending time with his now-girlfriend, Kylie, 28, at Jean Paul Gaultier’s Paris fashion week show.

The couple has been nearly inseparable in the years since. After being spotted together on several occasions over a two-year period, the pair made their red carpet debut in May 2025.

The following January, the “Dune” star publicly declared his love for Jenner for the first time while accepting the best actor award at the Critics Choice Awards.

Shortly after, a source exclusively told Page Six that the pair have been living together and were “basically married.”
