Lady GaGa: 'I wear my costumes to bed'

Lady GaGa has revealed that she often goes to bed in her stage costumes.

The 'Judas' singer explained that she regularly wakes up in the outfits dishevelled, having spent the night wearing them.

She said on The Ellen DeGeneres Show: "My best friends, who often will crash at hotels where I'm at... they will come visit me on the road, they always call me a beauty queen disaster.

"I wake up and my wig's falling off my head. My mole is on the other side of my face. My fake mole - it's not fake, it's surreal."

The popstar, who is godmother to Sir Elton John and David Furnish's 4-month-old son Zachary, admitted that she finds her success "overwhelming".

She added: "I'm 25 years old. I was asked to play Madison Square Garden. Sold out five nights and, quite frankly, it's very overwhelming."
