Larry Birkhead came out swinging tonight on CNN's "Larry King Live," telling TMZ's Harvey Levin that "Blonde Ambition," the new book by Rita Cosby, is "pure fiction" and should be sitting next to "Harry Potter."
Larry also responded to what Rita told FOX's Bill O'Reilly tonight, as to why the two former enemies now get along. Larry says he simply decided to put the best interests of his daughter first, so he buried the hatchet with Howard. Refuting what Rita claims in her book, Birkhead states flat out -- there were no secret deals between him and Stern.
Larry's bottom line -- he'll see Rita (and everyone else) in court.
