Whoa! We never woulda seen this coming! Kaia Gerber, 18, and SNL funnyman/boyfriend du jour Pete Davidson, 25, enjoyed what appeared to be a romantic lunch date in SoHo on Sunday, according to fans who spotted the two together.

"They were having lunch and laughing together as they ate,” an eyewitness told Us Weekly. “Pete appeared happy to be with Kaia, and she seemed like she was into Pete, though there was no PDA."

Well, maybe there was no PDA ... but that's sure to come! The pair ate at Sadelle's in lower Manhattan around 2pm on Sunday and stayed at the restaurant for about an hour before leaving together, according to Us. Wednesday, Pete was spotted leaving Kaia's NYC apartment!!

Davidson recently split from actress/model Andie MacDowell's daughter Margaret Qualley. The two started dating in August around the time they attended the premiere of her film Seberg at the Venice Film Festival. Of course Pete dated Kate Beckinsale for about five months before Qualley and was engaged to Ariana Grande for four months before that. Dude gets around!
