{babes} Gaga beheads Barbie on stage

Lady Gaga served up an early Halloween stunt for the crowd at her show in Belfast, Northern Ireland on Saturday - she bit the head off a Barbie doll.

The Poker Face hitmaker was playing at the city's Odyssey Arena and gave the audience a gig to remember with her shocking stage antics.

And after beheading Barbie, the singer took her wild behaviour to a fiery new level - by playing a burning piano, according to Britain's The Sun.

After the show, the singer took to her Twitter.com page to post a picture of herself wearing a bloodied t-shirt with 'I Love Belfast' written on it, accompanied by the message, "For Halloween I'm going to be...a little monster!!!! I love you all so much! Celebrate yourself!"
