Howard Stern Files Libel Lawsuit Against Rita Cosby

Anna Nicole Smith's lawyer and companion, Howard Stern, filed a $US60 million libel lawsuit Tuesday against Rita Cosby and her publisher over a book she wrote that claims Stern and Smith's ex-boyfriend, Larry Birkhead, had a sexual encounter.

The suit, filed in federal court in New York, seeks $10 million in compensatory damages and $50 million in punitive damages from Cosby - who wrote Blonde Ambition: The Untold Story Behind Anna Nicole Smith's Death - and Hachette Book Group USA Inc.
