PHOTO GALLERY: Katy Perry’s Goes Hollywood

Katy Perry had the crowd a rocking last night at the Hollywood Palladium. Five lucky winners and a friend, who won our ticket giveaway on Socialite Life, got to attend the concert where she preformed her hits “I Kissed A Girl” and “Waking Up In Vegas.”

If you couldn’t attend the concert last night, you can see the show streaming live on starting August 30th at 6:00 pm PST.

After the show Katy must have done some heavy partying at H.Wood nightclub after the concert, because she’s seen covered with pieces of cake. Yummy.
