Lady Gaga is having sleepless nights worrying about her fans.
The 'Poker Face' singer is so caught up with fame that she struggles to get sleep at night.
"I'm already crazy. I'm a fearless person. I think it creeps up on you. I don't think it can be stopped. If my destiny is to lose my mind because of fame, then that's my destiny. But my passion still means more than anything," Contactmusic quoted her as saying.
"For some people, fame kills it and becomes more important than the music or the performance.
"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. And my passion is so strong I can't sleep - I haven't slept for three days," she added.
Despite her sleeping problems, she refuses to take any medication to help her relax.
"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 ut," she said.
