Simon Cowell plans to do a charity walk to celebrate his recovery from a broken back

A source told the Daily Mirror newspaper: "Simon is back to full fitness and has been telling pals he feels 110 percent.

"He jumped at the chance to do the charity walk as it’s a cause so close to his heart. He has a contacts book bulging with celebrity friends and rest assured they will all be getting calls about donating."

Simon - who has a seven-year-old son called Eric with Lauren - is a vice president of the charity and is determined to show his support by completing the walk.

The TV star previously admitted that even though he suffered a severe injury last year, the situation could actually have been a lot worse.

He shared: "It could have been a lot worse. When I saw the X-ray, I really nearly could have smashed my spine to pieces, so I literally wouldn’t have been able to walk."

Simon also recalled the moments after the crash, admitting it was a "surreal" situation.

He said: "I knew I’d broken my back the minute I landed. It was really, really kind of sudden and it hurt.

"You’re not supposed to move. I was thinking: ‘I’ve got to get back into the house because I can’t lie there’ … and made myself kind of get carried into my bedroom, which is right there at the beginning of the house ... And I’m lying there and I’m kind of passing out … It was surreal."
