Kylie Jenner Sports a Stunning Diamond Ring While Cheering on Boyfriend Timothée Chalamet at the Santa Barbara Film Festival.

Kylie Jenner was dazzling with her jewelry as she showed support for boyfriend Timothée Chalamet at the Santa Barbara International Film Festival.

The 27-year-old reality star and entrepreneur wore a stunning, square-cut diamond ring on her index finger as she attended the event at the Arlington Theater on Tuesday, February 11.

The night was especially significant as Chalamet, 29, received the Arlington Artist of the Year Award for his role in the Bob Dylan biopic A Complete Unknown.

In addition to the eye-catching piece on her index finger, Jenner sported a second large ring on her pinky, which she showed off in a close-up shot on her Instagram Stories.

The sparkling rings perfectly complemented her soft, pink-nude manicure and stood out against her bold, dark ensemble.

To watch Chalamet accept his award, Jenner wore an elegant black dress with a halter-neck and plunging neckline that gave a subtle glimpse of side boob, a look she also shared on Instagram.

Aside from her standout jewelry, Jenner kept her style understated.

Her hair was styled in a voluminous, bouncy blowout, and her makeup was fresh and natural, with a nude lip and a touch of blush.

During the event, Jenner sat closely beside Chalamet as they enjoyed a career retrospective of his work, a moment captured by the festival’s Instagram account.

Later, she cheered him on as he took the stage to accept his award, smiling as she clapped for him.

Jenner, who has been linked to Chalamet since April 2023, has accompanied him to numerous events, including the Wonka premiere, the Golden Globes, and a post-SNL afterparty in January.

A source told that Jenner enjoys supporting her boyfriend through awards season, sharing, “She knows how much his career means to him, and she wants to be there for him.”

The source added that Jenner is “extremely happy” and that the couple is “very serious,” with the entire Kardashian-Jenner family warmly accepting Chalamet.
