LOS ANGELES — Kylie Jenner has earned her wings, and her boyfriend, Oscar-nominated actor Timothée Chalamet, could not hide how proud he was.

The beauty mogul and reality star made a surprise runway debut at the 2026 Victoria's Secret Fashion Show on Sunday, October 18, at Sony Pictures Studios in Culver City, Los Angeles. It was her first time ever walking for the lingerie brand.

As she stepped out, cameras caught Chalamet in the front row smiling, clapping and cheering her on. A short clip of his reaction quickly went viral, with many fans calling him the most supportive partner in the room.

A US$50 million entrance

Jenner did not just walk the runway. She did it in one of the most expensive outfits in the show's history.

She wore the brand's famous Fantasy Bra, valued at US$50 million, the most expensive Fantasy Bra ever and reportedly about US$35 million more than the previous record. Made of gold and set with 4,410 natural diamonds, it was paired with a sheer white mini skirt and huge white feathered angel wings.

It was also a comeback moment for the Fantasy Bra itself. Victoria's Secret had not unveiled one since 2018, making Jenner's appearance one of the big talking points of the night.

Front-row support

While Jenner commanded the runway, Chalamet made his own impression from the audience. Dressed in a black top and sunglasses, the Marty Supreme star sat in the front row alongside Kylie's mother, Kris Jenner, and her partner, Corey Gamble.

The viral clip shows Chalamet beaming, clapping and cheering as his girlfriend walked past. Kris was seen smiling and filming the moment on her phone.

A private couple's public moments

Jenner and Chalamet reportedly began dating in 2023. They have kept their relationship largely private and rarely discuss it in interviews, but they often turn up to support each other at big moments.

Earlier this year, Chalamet won Best Actor at the Critics' Choice Awards for Marty Supreme and publicly thanked Jenner, his partner of three years, in his speech. "Thank you for our foundation. I love you," he said. He went on to win the Golden Globe for Best Actor, with Jenner by his side.

Jenner has returned the support. She has said she watched Chalamet's film Wonka seven times, and on Sunday night, it was his turn to cheer from the audience.

A family affair

Kylie is not the first of her family to walk for Victoria's Secret. Her older sister, supermodel Kendall Jenner, walked in the brand's shows in the 2010s. Kylie's debut makes her the latest Kardashian-Jenner to take on one of fashion's most famous runways, a long way from her early days on Keeping Up with the Kardashians.

Today, the 29-year-old is best known as a businesswoman, with beauty and fashion brands including Kylie Cosmetics and the clothing label Khy.

What's next for the couple

Chalamet is expected to be busy soon with the global press tour for Dune: Part Three, in which he returns as Paul Atreides. If Sunday night is anything to go by, he may have a familiar face cheering him on.
