Kinky Cosby: Names Drug Party Pals!

Perv will do & say anything to save own skin at SEX ATTACK trial.

COWARDLY Bill Cosby has turned into a shameful stool pigeon and is ratting on his old showbiz pals — linking them to a disgusting Hollywood sex ring in his frantic bid to beat a rape rap.

As his June trial for drugging and sexually abusing unconscious Andrea Constand, then 30, in 2004 approaches, the despicable star plans to get off by naming other top stars, as part of a Hollywood sex ring — because they can testify drugs and sex were common events at Tinseltown parties.

He reportedly hopes to have his former co-stars John Amos and Jimmie Walker, along with Harvey Keitel and “Six Million Dollar Man” hunk Lee Majors, tell jurors about the old Hollywood party scene.

“Cosby knows his back is to the wall and that his only hope is to give up the names of other celebs involved in a parade of parties where impressionable young women were targeted,” said a source close to the case.
