Spencer PRATT to write a BOOK, oh brother!

Sources reveal exclusively to PerezHilton.com that Spencer Pratt is "in talks" to release an autobiographical book and he's ready to tell all.

"He's close to signing a deal," an insider aware of the negotiations tells us. "He will talk about L.C., Brody and everything else you'd wanna know."

Will he talk about the sex tape? The drugs? LC and adderall? Heidi being insane? These are things I want to know!
