Is nothing sacred, Lady Gaga? Apparently not. Poor Santa Claus took a stiletto heel to the head at the singer's Monsterball London concert, reports the Telegraph. Someone tossed the small stuffed Santa onto the stage and Gaga first tried to bite its head off, à la Ozzy Osbourne. But the head wouldn't budge, so she mangled the doll by grinding her heel into his neck. "I hate the holidays," she shouted to an appreciative audience. "I'm alone and miserable you dumb bit of joy!" She also declared the Claus "pregnant with chemicals and not suited for children." Then: "Now that I've killed Santa, what am I going to do with all of you?" Can't wait to see.
