Sydney Sweeney is seeing Scooter Braun.
Sweeney recently made headlines for holding hands at Universal Studios Halloween Horror Nights in Los Angeles with her new man Scooter Braun. They were joined by Sweeney's mother, Lisa, and father, Steven, as five private security guards and VIP tour guides escorted them.
The executive, 44, wore a gray sweatshirt alongside Sydney, who kept it casual in a pair of jeans.
"They talk every day and see each other often. It is hot and heavy," an insider dished. "I don't want to say the L word, but it feels like the L word. They seem very much in love, or at least incredibly in lust. The attraction is she is hot as can be, and he is an old soul who is helping her guide her way through sudden fame and her exploding career. He gives great advice. They have what each other wants."
Sydney Sweeney was previously engaged.
Sydney was previously engaged to Jonathan Davino, but they called it off.
“I'm learning a lot about myself, spending more time with my friends. And I'm loving it,” she previously said of being single.
