Lady Gaga outed herself as the ultimate Christmas Grinch by biting off the head of a Santa doll at a concert in the UK on the weekend.

A fan handed the 2011 Grammy nominee the toy during her sold out show at 02 Arena, prompting an unexpected response from the pop superstar.

Billboard’s Artist of the Year admitted she loved the holidays but ripped the doll’s head off saying that this is “for those of you who are feeling lonely this Christmas”.

She then stomped on Santa with her stiletto boot and told the crowd “I hate the holidays! I’m alone and miserable!”

The fame monster then threw the toy back into the crowd saying it was “pregnant with chemicals not fit for children”.

Looks like someone has a bad case of the Christmas blues.
