Serial dater Audrina Patridge and Ryan Cabrera were spotted trying to hide in the back of a car leaving West Hollywood's Wonderland nightclub last night.

Might these two hotties be dating?

A source said singer Ryan, who's sporting some serious Pauly D hair, and The Hills star were spotted getting cozy together during their night at the club.

According to reports, the pair had also been spotted together on Sunday at a performance of Broadway's "Rock of Ages." Maybe there's something to it!

Then again, it's Audrina Patridge. She's pretty much the queen of on-off quasi-dating. As long as it's not with Justin-Bobby, though, that's all good ...
