HOLLYWOOD - Anna Nicole Smith's longtime companion Howard K. Stern is suing a journalist for "exploiting" the memory of the late glamour model.

Stern filed a $60 million lawsuit against Rita Cosby on Tuesday over "false allegations" in her new tome Blonde Ambition: The Untold Story Behind Anna Nicole Smith's Death.

The book claims Stern and Larry Birkhead--the father of Smith's daughter Dannielynn--were lovers who plotted to get control of the late star's estate. Cosby, a former MSNBC correspondent, claims there is a sex tape to prove the pair were lovers.

But Stern's attorney, L. Lin Wood, has furiously denied the accusations.

Wood says, "Blonde Ambition purports to be a 'tell-all' book, but it can only be accurately described as a 'tell-all-lies' book.

"And I am sure Howard and the estate and everyone else involved is going to sue her, too. This is just nonsense... None of it is true."

Birkhead has denied a sex tape exists and has also threatened to sue.

Smith passed away earlier this year.
