The 22-year-old "Silver Linings Playbook" star was spotted dining with the "Warm Bodies" actor at a West Hollywood restaurant back in April. And now the two are back together for "X-Men" promotional duties at San Diego Comic-Con, where they've been seen hamming it up for photographers and walking around together (which usually amounts to a relationship in the gossip world).
A source has told US Weekly that the two "started kissing" one day in April.
"They started the shoot in April as friends, and then one day they just started kissing," the source said. "One thing led to another and they hooked up. All her old feelings came rushing back. Now they're fully back on."
Hoult and Lawrence last ended their two-year relationship in January.
