Pete, 25, was spotted holding hands with actress Kate Beckinsale, 45, following one of his stand-up gigs in LA over the weekend.
The pair left in a car together while TMZ got photos of them getting extremely close to one another.
According to E! News, he and friends Machine Gun Kelly arrived at the party together early on. After standing and chatting closely with Kate on the dance floor, they went and got cosy on a couch.
"She was very flirty with him and there were definitely some vibes going on," a source described. "Pete was smiling and laughing with her and she was all about him."
About an hour after this, the pair left the party.
A second source, however, did add, "They did not go home together."
We're just happy to see him happy again!
