Chris Martin has therapy because he can't sleep.

The Coldplay frontman - who has two children Apple, seven, and five-year-old Moses with wife Gwyneth Paltrow - sought professional help in order to cut down on The Restless nights he frequently experiences.

Asked if it is true he sees a therapist once every time he releases an album, he said: "No, bit more than that. I have a lot of trouble sleeping. It's to do with that and what to take and not to take."

When he does get some sleep, Chris is plagued by nightmares, usually connected with the group's performances.

He explained: "I'll give you a classic dream I had last night. We were playing on Letterman and I was in a different key to everyone else. David Letterman came on and said, 'Can you stop? This is not very good. Can you do the other song?' And then, we start doing the other one and my shoe falls off.

"It goes a bit surreal after that but it always starts with playing a concert and there's some insurmountable problem. I have many more nightmares than dreams; probably nine to one. Real life is much better."

A song once came to Chris in a dream, which he showed to David Bowie - but the legendary singer told him it wasn't very good.

Chris recalled: "He said, 'I'm really sorry, but it's not your best.' He was very kind about it. I was like, 'You know what? You're probably right'. It might have been written by sleeping pills so I wasn't too personally offended."
