Both Britney Spears’ unofficial manager and paparazzo lover are shopping proposals for a pair of tell-all books about the pop star’s psychotic breakdown to American publishers.

”That should tell you something about their true devotion to Britney and her interests,” a Spears insider says of Sam Lutfi and Adnan Ghalib.

”These guys better get those books out real fast,” says a former member of Britney’s legal team. ”This story is changing daily. Unless those books include information the public already doesn’t know, those ‘tell-alls’ won’t mean much, given what may happen to Britney in the days and weeks to come.”
