The 24-year-old actor, who played Beast in 'X-Men: Days of Future Past', was spotted with Keough at a party on July 23, reported Ace Showbiz.
"They were sitting arm-in-arm in a booth with Adam Lambert and Charl Brown. Hoult and Lisa Marie Presley's daughter looked cozy," an onlooker said.
Hoult and Lawrence broke up briefly in 2013. In an interview, the Oscar-winning actress shared that she and Hoult ignore each other when they are busy.
"It's hard when you're both working. It's important to keep your individuality when you're a couple and keep your own life. When we're busy, we agree to mutually ignore each other. Not completely, but neither of us gets mad when the other doesn't text back or call. Life's super busy. Obviously you know what they're doing, and you trust them," she had said.
