Britney Spears has been the center of speculation that 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.

The “Womanizer” singer has already been signed up by a literary agent and will put pen to paper following her sell-out world tour.

A source revealed: “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.”

The source added: “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.”

However, one U.S. publishing insider said that it’s unlikely that the pop princess would get anything near the amount being reported.The insider revealed: “That seems ridiculously high for a book deal. Even though she’s a huge star, that doesn’t mean anyone wants to read an autobiography by her.

To make back that much of an advance, the publisher would have to sell Harry Potter-size numbers.”So while we would love to see Britney finally tell her complete side of the story — from Mickey Mouse Club to divorced mother of two — we’re not holding our breath.
