Macy Gray Surprises The Blue Ball With Live Set, KOL Cover

This past Saturday at Siren Studios in Hollywood was The Blue Ball, a celebration of Perez Hilton's 33rd Birthday — which featured every attendee decked out in blue. One highlight of the very fun event (other than the bouncey-bounce castle!) was Macy Gray's surprise performance.

Complete with a stage-full of instrumentalists, Macy belted out her hits, new material and this especially rocking cover of Coachella headliners Kings of Leon, "Sex on Fire." Other performers included Dita Von Teese, Debbie Gibson, Selena Gomez, and Glee's Darren Criss.

And... the original.
