The ‘Born This Way’ singer – real name Stefani Germanotta - is often the subject of her friends’ jokes because she rarely takes her extravagant stage make-up off before going to bed.

She said: “I’ve got to wash my face at some point.

“I do get laughed at quite a bit by all my friends because they say I go to sleep a lot with my make-up on. But I say that I have to be ready for the men in my dreams!”

The 25-year-old pop star - who is single after splitting from boyfriend Luc Carl – has admitted she started experimenting with unusual make-up while she was still in school, making her a target for classroom bullies.

Gaga said: “They’d say, ‘Why do you do your make-up like that, what's with your eyebrows?'

"I used to do these really big Evita brows. I used to self-tan, and I had this really intense tan in school, and people would say, 'Why the f**k are you so orange, why do you do your hair that way, are you a dyke?'
"I used to be called a sl*t … I didn't even want to go to school sometimes.”
