Uh oh, looks like someone's seeking revenge.
We are hearing that Marc Jacobs' ex, Jason Preston, is writing an explosive tell all book about the designer.
Jason is said to be tired of getting trashed by the media and wants to reveal who the real Marc Jacobs is.
No word on a official release, but our source tells us that it's practically a done deal.
Would U read it???
