Lady GaGa failed to get in the festive spirit during her performance at London's O2 Arena on Thursday (16Dec10) - she bit the head off a Santa Claus doll before stamping on its mangled remains.
The Poker Face star returned to the U.K. capital with her Monster Ball tour and was at her controversial best when a fan threw a doll of Father Christmas onto the stage.
Gaga accepted the gift - but then stunned the audience by biting into it with her teeth before finishing it off with the heel of her shoe.
She told her victim, "I hate the holidays. I'm alone and miserable you f**king stuffed little toy."
But Gaga made up for her aggression later in the set, by reading segments of a book another devotee handed to her.
