Lady Gaga has revealed that she finds it hard to sleep - because her music is always on her mind.

The Telephone singer claimed that she has suffered from sleepless nights since she hit the big time last year.

GaGa told Ok! Magazine: “My passion is so strong I can’t sleep - I haven’t slept for three days,”

“I lie in bed and try to pray and breathe. I have a very overactive mind. I’m the sort of person who’d never take medication to calm myself. It’s maddening. But I love what comes out.”

The 24-year old, who recently celebrated her birthday added: “If my destiny is to lose my mind because of fame, then that’s my destiny. But my passion still means more than anything. For some people, fame kills it and becomes more important than the music or the performance.”

She said: “But for me fame is like rocket fuel. The more my fans like what I’m doing, the more I want to give back to them.”
