Gwen Stefani Arrives at Hammerstein Ballroom

Looking something like a zebra, hollaback girl Gwen Stefani just arrived at Hammerstein Ballroom in midtown, where later tonight she will perform with Alicia Keys for the Black Ball 2007. The proceeds from the evening will go to the AIDS charity Keep a Child Alive.
