Speidi: Rated XXX?

Spencer Pratt is hawking a supposed sex tape starring soon-to-be ex wife Heidi Montag, he confirms to

"I've been making films since I was in the 7th grade," Pratt tells Us exclusively. "I'm looking forward
to people seeing my directorial debut!"

Steve Hirsch, co-CEO of ubiquitous porn company Vivid Entertainment, told TMZ that he spoke with Pratt Friday about the explicit video, noting "We are in early negotiations to possibly come to terms for a deal."

It's a busy time of wheeling and dealing for Pratt.

On Thursday, the reality villain told  that he is writing a tell-all book about his relationship with Montag.

"My last book, How to be Famous, didn't make the New York Times best-seller list because it was in the self-help section," Pratt told Us. "This one is going to be totally different. I'm not holding anything back."

Montag, 23, subsequently told TMZ that she might sue to stop the book. She filed for divorce in July after about 15 months of marriage. Barring any reconciliations, their divorce will be finalized on Valentine's Day of next year.
