Andy, Bethenny, and Brad Do The Hustle

Andy Cohen, Bethenny Frankel, and former Rachel Zoe protégé Brad Goreski were shakin' their groove things on Studio 54's dance floor Tuesday night. The Bravolebs showed up at the world's most famous nightclub as it reopened for "One Night Only" at its original location to celebrate SiriusXM's new Studio 54 radio station. 

Andy -- sporting a white shirt, purple tie, and jeans -- helped unveil the Studio 54 marquee. Once inside, he changed into a fitted black jacket and punkish Mickey Mouse tee.  Showbiz 411 says the dance floor "throbbed" as original Studio 54 DJs Nicky Siano and Leroy Washington spun the sounds of Gloria Gaynor and Donna Summer circa 1977.  Brad sported a dashing red blazer, white tie, and his signature black specs. Bethenny was a disco diva in a black silk top, gold belt, and black sequined hot pants (yes!).

Andy, Bethenny, and Brad were Tweeting like crazy about the night. Andy tweeted at Bethenny, "See u at Studio 54 lady RT @Bethenny: @BravoAndy running like a thief in the night. THIS is what I live for." Later, Bethenny tweeted, "'One night only' at studio 54.this is everything I LOVE .I'm a disco queen!any of you out there??? twitpic.com/72fu7o."
