She's baaaack.

We haven't heard from Heidi Montag (or her obnoxious other half Spencer Pratt, Praise Jesus) in quite some time.Well.... she's back.  This weekend she hosted a pool party at Wet Republic in Vegas.  Apparently she worked out for 14 hours a day leading up to her hosting gig.  WTF???  By her side was Hef's recent ex-fiance, who attended the party on her would be wedding day.  Classy.   Don't worry
