Kylie Jenner made her Victoria’s Secret runway debut in a bra made entirely from gold and diamonds - and Timothée Chalamet was absolutely loving it.
Having been together for over three years, the Oscar nominee, 30, watched on as his girlfriend, 29, rocked up in a record-breaking piece designed by luxury jewellery house Jacob & Co at Sony Pictures Studios in Culver City, LA on Sunday (18 October).
Sat alongside The Kardashians star's mum Kris, the pair smiled and clapped for Kylie, who wore a bra with '4,410 natural diamonds surrounding a 75.54-carat radiant-cut Fancy Vivid yellow diamond', according to Vogue.
"It took 15 craftspeople more than 1,000 hours to build it, and the finished product weighs just under four pounds. The total cost? A whopping $50 million, the highest price (by some $35 million) for a Fantasy Bra to date," the fashion outlet explains.

It was also custom-engineered to fit the Kylie Cosmetics founder's body while allowing her to move comfortably on the runway.
Notably, the bra was made entirely from gold and diamonds, with no fabric whatsoever.
Over on Instagram, Kylie called it the 'best day ever'.

Adam Selman, chief creative officer at Victoria’s Secret, said: “We thought, OK, how do we do this in a really fun, excessive way? Because that’s what it is: a truly excessive piece of jewelry and artistry. It’s almost museum quality.”
Jacob Arabo of Jacob & Co noted that 'even with exact measurements, what looks good on paper doesn’t always work the same way on the body'.
“Every curve, every diamond, and every piece of gold had to be carefully placed so the bra would be both beautiful and comfortable,” Arabo said.
While Jenner and Chalamet often support each other's careers - Jenner told Kid Cudi's Big Bro podcast earlier this year she'd seen Chalamet's Wonka seven times - they are often private and rarely answer questions about their relationship.

During a Q&A for Chalamet's 2025 movie Marty Supreme, the actor was asked if he thinks he will ever get married.
"Wow, that's so personal," he said. "You're going to get me in trouble, man."
However, he appeared to say 'yes' on the marriage question in a fan video.
However, when Vogue tried to get him to talk about Jenner in a November 2025 profile piece, he simply responded: "I just don’t have anything to say."

At the Critics' Choice Awards earlier this year, Chalamet did make a point of thanking Jenner on stage, saying: "Thank you for our foundation. I love you. I couldn’t do this without you. Thank you from the bottom of my heart."
Jenner told Vanity Fair that 'of course' it's fun to be given a shoutout on stage.
She also said she and Chalamet host poker nights together, with other Hollywood stars attending.
She said on an episode of The Kardashians when asked about navigating her relationship with Chalamet in the public eye: "I have to live my life. I can’t live for whatever everyone else wants me to do. I just have to try to do what’s best for me every day."
