The on-again couple were joined with a number of their X-Men: Days of Future Past costars for a private movie screening, thanks to their buddy and fellow onscreen mutant Hugh Jackman.
"Took the Xmen gang to screening of The Butler. Loved it.. Huge Congrats to #leedaniels@oprah#thebutler," the actor wrote alongside a photo of the group in the theater.
And whaddya know—right there, front and center, are J. Law and Hoult looking cute and oh-so adorable as they sit closely next to each other with big smiles on their faces.
The young pair were also spotted together arriving at the film's private wrap party in Montreal, Canada, at the club CINQ in downtown over the weekend.
Looking trendy and cazh, Lawrence strut her curves while wearing a black, sheer spaghetti-strap tank top with a neon bandage skirt and black peep-toe heels, while Hoult looked handsome in cuffed pants and a gray T-shirt that was revealed through an open salmon button-down.
The duo, who split in January of this year, reportedly rekindled their romance after reuniting to shoot the X-Men flick. Lawrence even spoke about her breakup with the young star in Vogue's September issue.
"I wake up earlier in the morning when I have new sponges. That counter doesn't even see it coming. [Hoult] would never wring them out. We were in the kitchen once, and I picked up the sponge, and it was soapy and wet, and I was like, 'See? These are the kinds of things that make me think we are never going to work.'"
Luckily, they worked through it.
