Lady GaGa experienced a stage mishap when she performed one of her hits at Auckland, New Zealand concert on Sunday, June 10. A dancer accidentally hit her in the head with a pole which is used as stage prop in her "Judas" performance. GaGa touched her head briefly but went on singing before going to the backstage. She suffered concussion from the hit, telling her audience "I want to apologize. I did hit my head and I think I may have a concussion but don't you worry I will finish this show."
