It could be the biggest bombshell yet in the Bill Cosby scandal.
A former Playboy Bunny is speaking out to INSIDE EDITION, accusing Cosby of sexually assaulting her and at least 12 other Bunnies in the 1960s.
She told INSIDE EDITION, "I do know of 12 other former Bunnies that were drugged and raped by Bill Cosby. They're frightened to come forward. They have lives, they have children, they have grandchildren, they're involved in their community, and they're afraid to come forward."
P.J. Masten claims that she was drugged and raped by Cosby who was a frequent guest of Playboy founder Hugh Hefner at his mansion.
She said, "He had poured me a drink with ice and I drank a little bit of it, and the next thing I remember was four o'clock in the morning. I was in his bed. He was next to me. I was naked. I was bruised."
Masten said that she told her Playboy Bunny supervisor what happened and got this response: "I was instructed to keep my mouth closed."
Masten has made claims against famous personalities before. In 1997, with famed attorney Gloria Allred at her side, she claimed that sportscaster Marv Albert bit her and tried to force her to commit a sex act, a claim Albert denied.
At the time, Albert was on trial for attacking another woman. He later pled guilty to a lesser charge.
Other Playboy employees have also come forward, including Victoria Valentino who was Playmate of the Month in September 1963. She recently told INSIDE EDITION that Cosby drugged and sexually assaulted her.
In the interview, Valentino said, "It's a perfect milieu for a predator to schmooze in."
Masten also told INSIDE EDITION, "I was the Bunny mother. My job was to protect and take care of these girls, make sure none of this happened to them. And it happened to me."
As if things couldn't get any worse for the embattled Cosby, now his star on Hollywood's Walk of Fame has been vandalized. Someone scrawled "Rapist" on it, three times.
The U.S. Navy has just announced that it has revoked the honorary title of Chief Petty Officer it awarded Cosby in 2011, saying in a statement: "The Navy is taking action because allegations against Mr. Cosby are very serious and are in conflict with the Navy's core values of honor, courage and commitment."

Masten said, "He is a serial rapist. The man is a serial rapist."
Cosby has not commented on Masten's allegation, but his lawyer has repeatedly denied such accusations in the past.
