Things went from D-list to A-list for the for the first time in Hot Mess history on Sunday. Danity Kane's Aubrey O'Day stopped the show at Sunday night's Hot Mess party at Porky's.  Aubrey appeared, seemingly out of no where, and hopped on the bar with a mic to sing the Danity Kane hit single, Show Stopper. 

Aubrey was very down to earth and even joked with the crowd introducing the tons of drag queens who joined her on the bar as the new "Danity Kane."

Hot Mess was packed from wall to wall with hotties on Sunday night reminding everyone why it was voted Best Gay Lounge night by HX magazine.

And by the way, she's totally not pregnant!!
