Sydney Sweeney throws star-studded birthday bash for boyfriend Scooter Braun

Sydney Sweeney threw an early star-studded birthday party for her boyfriend, Scooter Braun, with a special performance by Warren G.

The “Euphoria” alum surprised the former music executive with a bash alongside A-list attendees, including Jessica Alba, Tom Hanks and Rita Wilson, at a Santa Monica, California, venue on Saturday night, Page Six is told.

“She had a basketball hoop set up. Warren G performed ‘Regulate,’ Scooter’s favorite,” an insider told us.

Sweeney, 28, and Braun, whose 45th birthday falls on June 18, were seen sporting Connecticut Flame basketball jerseys with the number 45 in an Instagram photo with friends.

The couple’s milestone comes after they started dating in September 2025, months after they connected at Amazon billionaire Jeff Bezos and Lauren Sanchez’s wedding in Venice, Italy, that June.

Since then, they haven’t shied away from PDA-packed outings and date nights around Los Angeles.

Sweeney and Braun recently made their romance Instagram-official with sweet photos from their time at the 2026 Stagecoach Music Festival in April.

The photodump included a snap of the “Christy” star on Braun’s shoulders as they watched a performance from the audience.

Another photo showed Braun holding the actress in his arms, while a third saw them posing in a photo booth.

Additionally, Sweeney shared clips of herself and Braun line dancing.

“cowboy kind of weekend,” she captioned the snap.

Most recently, Braun planned a special date night for the “Nobody Wants This” star and took her to Times Square in New York City for her first time last month.

“When you’re in bed at 11pm and your girl says “I’ve never been to Times Square….,” Braun captioned a video of himself and Sweeney heading to the tourist attraction.

The duo rode rental bikes throughout the Big Apple before eventually reaching their location.

Sweeney went incognito in a hoodie and sunglasses, as she smiled widely in a crowd of people.
