London's O2 arena Friday night, a Lady Gaga fan threw a Santa Claus doll In Toronto Concert - Full Video

London's O2 arena Friday night, a Lady Gaga fan threw a Santa Claus doll up onto the stage while the star was performing. Instead of taking it and maybe making a wish for Christmas, Lady Gaga ripped a page out of Ozzie Osbourne's book -- and bit right into its neck.

"I do like Christmas, but for those of you feeling lonely this Christmas, just to keep everyone happy," she said, before biting into its merry neck.

"I hate the holidays. I'm alone and miserable you f**king stuffed little toy," the Grammy-winning singer yelled out as she finished the beheading with the heel of her shoe. No doubt she can expect coal in her stocking this year.
