Party pics: Gridlock New Year's Eve at Paramount Studios back lot

She has her party hat on

America’s favorite bi-curious pop star put on her cherry ChapStick for Gridlock’s mind-blowing party at Paramount Pictures Studios’ New York street back lot. This event was the toast of the town with performances by Katy Perry and LMFAO. In addition to the light shows, there was also massive amounts of confetti, real snow (from a snow blower, of course) and eight DJs (Skeet Skeet, Guns N Bombs, Pase Rock and Cool Whip to name a few) on four live stages!
