Critics have been quick to write-off Britney Spears whenever her life has threatened to spiral out of control - but this time she's beaten them to it!

The ink should soon be dry on a £10million publishing deal for the princess of pop to give a no-holds-barred account of her crazy career.

Brit, 27, has already been signed up by a literary agent and will put pen to paper following her sell-out world tour.

Our source reveals: "There have been numerous unofficial biographies printed about Britney, but she's never agreed to pen her own tome - until now. "And some of the stories she's got are absolute dynamite. She's kept diaries so there's nothing she'll leave out unless she wants to.

"If the deal goes ahead she will write between three and five books throughout the next decade - it's one of the most lucrative book deals in showbiz history.

"Britney will talk frankly about growing up and how she went off the rails. It'll be a gripping read."

It's certainly one way for her to turn over a new leaf...
