Cutest couple ever alert?

Lauren Conrad not only broke up with Dancing with the Stars pro Derek Hough recently, but the 25-year-old isn't wasting any time moving on to her next guy ...

Gossip Girl star Chace Crawford!

A source tells Us Weekly that the Hills alum was spotted "making out" with the actor. Their reps deny the hookup ... but there's no denying this kind of hotness!

Lauren Conrad and Chace Crawford kicked off the hot night of flirting at L.A.'s Voyeur nightclub and later connected at a party at actor Shawn Pyfrom's house.

"There's always been an attraction between them," an insider says. "[But] Lauren is really enjoying herself lately. She's not taking anything too seriously!"

That's what they all say. Play on, players.
