Realityween

The lure of the bright lights, casinos and never-ending costume parties reeled in a bevy of reality stars this weekend. Yes, the A List was frolicking alongside Hollywood's most shameless in Sin City. While the tables had a firm hold on me and my flapper costume all night, these reality stars shook up the dance floors in Vegas' hottest clubs.

The A List can't seem to escape Speidi in Vegas. Appearing at Caesar Palace's Pure nightclub during both of my visits were a pre and post-breakup Spencer Pratt and Heidi Montag. While Spencer went the alien route, Heidi opted to dress as herself, post-surgery of course.

Leaving the Jersey Shore for Sin City, The Situation and Snooki each made an appearance at JET nightclub in my home away from home, the Mirage. The former Dancing with the Stars contestant appears to have lost weight, but I'm sure his abs remain intact. As for the Princess of Poughkeepsie? She turned up as the Pickle Princess.

She left the Playboy mansion behind, but Peepshow star Holly Madison is still a California girl at heart. The professional striptease star covered up as Katy Perry this Halloween.

From The Bank at the Bellagio, former Hills queen Audrina Patridge showed off her toned DWTS body. Tony Dovolani really does do the body well.

Trying to hold onto his 15 minutes of fame, Jersey Shore star Pauly D latched onto another pop icon, Justin Bieber, while at Moon in the Palms. Orange you glad the real Justin doesn't GTL?
