Robbie Williams won't tour in case he has a nervous breakdown.

The 'Bodies' star - who recently announced he will make his live comeback at the BBC Electric Proms in London later this month - is refusing to play any more concerts as he is terrified of the effect months on the road will have on his mental health.

He said: "I cannot imagine touring in the near future. I've smashed my head against a wall too many times and I know it's harder than I am.

"I felt great when I started to promote a record but it soon began to kill me. I felt worse when on tour. I suffered a nervous breakdown and checked into rehab."

On his last tour, 2006's 'Close Encounters', the 'Let Me Entertain You' hitmaker was forced to cancel several dates in Asia due to exhaustion.

Although he is looking forward to making his live return, Robbie struggles to enjoy himself when he is on stage because of "terrifying" nerves.

He confessed recently: "I get tremendous stage fright that's getting in the way of me enjoying it... it's terrifying. I want to find a way around it."

In order to avoid disappointing fans around the world, Robbie has now announced his comeback show - which sold out within minutes of tickets going on sale - will be broadcast live in over 200 cinemas around the world, with the footage aired in South Africa and Australia a few weeks after the October 20 performance.

Robbie said: "It's very exciting to think that a one-off performance I play in London can be seen simultaneously by people all across the world".
