Hills Smackdown! Spencer's Taking Names And Throwing Punches

Everyone's heard that Spencer and Heidi are getting into some serious relationship drama on Season 5 of Hills. But did you know that all those Spencer's-stepping-out-on-Heidi(!?) rumors started when Cameron told Stephanie a little story involving Mr. Pratt and a hottie female bartender?

Check out an explosive PopEater sneak peek from the season premiere of The Hills, and watch as Spencer goes from (allegedly) hitting on the hired help -- to REALLY hitting on his sister's then-boyfriend.

It officially just got real, dawg.
