Britney Spears' rise to stardom and subsequent descent into pop wreckdom may be turned into a Hollywood movie - if the singer's mother Lynne has her way.

According to insiders, Lynne is convinced that her recently-published memoir Through The Storm will be a hit on the big screen.

"She's pitching the book around to studios,” says a source close to the Spears matriarch.

It's been reported that rising star Anna Faris is in the frame to play Britney, but Lynne has another - less obvious - choice in mind.

The source tells The Sun that "she even says she wants Julia Roberts to play her. It's insane!"
