"The Hills" accused of being trashy?

The people behind "The Hills" are in a legal war over the live season finale -- accused of being even trashier than the people on the show.

The guy who owns the Beverly Hills mansion where MTV shot the "Live from the Hills Season Finale" claims when he rented the place out for the show in 2008, he was promised it would be returned in "the same condition." What he got back, he claims, was a disaster area.

According to a lawsuit filed today in L.A. County Superior Court, Igor Greenberg claims MTV and New Productions Inc. "caused extensive damage to the property in at least the amount of $158,250.07" -- and he wants them to fork over the cash.

Sure, it's meaningless, stupid drama -- but so is everything else that has to do with that show.
