When Heidi Montag and Audrina Patridge meet for lunch and Heidi asks A-Pat for a girls night out (with Stephanie Pratt), you know there's gonna be drama!

Lauren Conrad - who for the most part is actually working in this episode, with BFF Whitney Port - is none too pleased about this little club outing.

More significant, though, is the brawl that goes down between Spencer Pratt and Heidi Montag when he crashes her night out -and hits on other girls!

That's just the beginning of this drama, folks. Click on our full episode guide for the rundown of last night's episode of The Hills, "Girls Night Out."
