Scooter Braun wished his girlfriend, Sydney Sweeney, a happy 29th birthday as he praised their strong year-long relationship.

The music exec, 45, posted a video to social media Saturday of the pair dancing and kissing in front of a lit-up castle, to the tune of Mitski’s “My Love Mine All Mine.”

“Happy birthday to the woman who is the exception to every rule,” he captioned the post, adding that she was a person who “surprised” him and showed him “how life with true partnership can be lived.”

Braun continued, “You make me smile harder, laugh louder, adventure more, and dream bigger. You’ve made the ordinary feel exciting and the future feel like something I can’t wait to get to.”

“A giggle can change an entire day,” he added. “And I love how corny we can be together, because nothing else matters. There are a million things I could say, but the ones that matter most are just for you.

“Happy birthday Syd. Many more celebrations ahead. I love you ❤️,” he concluded the sweet message.

Sweeney and Braun have been spending time steadily together ever since meeting at Jeff Bezos and Lauren Sanchez’s Venice, Italy wedding in June 2025, with a source telling Page Six that Braun was “obsessed” with Sweeney and began “pursuing” her right away.

By late September, Braun had already met Sweeney’s parents, enjoying a double date with them at Halloween Horror Nights at Universal Studios Hollywood in Los Angeles.

The pair hard-launched their romance on social media this April after attending Stagecoach Music Festival in Indio, California.together, posting cozy pics with their arms around each other and goofing around in a photo booth.

Earlier this month, the two took things to an even more serious level, with the “Euphoria” alum spending time with Braun’s kids, Jagger Joseph, 11, Levi Magnus, 9, and Hart Violet, 7, at a smoothie run in Los Angeles.

Braun and Sweeney followed that up immediately with a trip to where it all started for them — Venice, Italy — spending romantic time together while Sweeney served as an ambassador for Armani Beauty, the official beauty sponsor of the 83rd Venice International Film Festival.

Sweeney was previously engaged to businessman Jonathan Davino, whom she broke up with in March 2025 after nearly seven years together.

Braun, meanwhile, was previously married to Yael Cohen, 39, from 2014 to 2021. They finalized their divorce in 2022.
