The beauty became one of the 77-year-old comedian's most high-profile accusers in December (14), when she detailed her own encounter with Cosby in the 1980s for a Vanity Fair article.

In the piece, she claimed the actor had tried to drug her by allegedly slipping something into her coffee during a visit to his California home while she auditioned for a part in his sitcom, The Cosby Show. After realising something wasn't right, Johnson flew into a rage and hurled expletives at the veteran TV star for his reported bad behaviour, prompting him to forcibly kick her out of his house and send her packing in a taxi.

Her memories of the close call echoed elements of stories told by dozens of other alleged victims, but Cosby's lawyers have maintained all the accusations of sexual assault and inappropriate behaviour are false.

The controversy took a shocking turn on Monday (06Jul15), when old court documents from a 2005 sex case against Cosby were unsealed. In his testimony, the actor, who has never been charged with any sex crime, confessed to giving former Temple University employee Andrea Constand drugs after she accused him of assault. He also admitted to obtaining powerful sedative Quaaludes with the intent of giving them to young women he wanted to sleep with.

The papers have only now been released as the lawsuit was settled out of court.

The revelation prompted a new backlash against Cosby, but Johnson, 62, claims she "wasn't surprised at all".

She tells U.S. breakfast show Today, "I knew that... eventually, it was going to come to light, so I wasn't surprised. I'm just very happy for the victims that they have some sense of peace and validation."

In a statement to People magazine, she continues, "It is unfortunate the amount of proof required to make a woman's voice valid.

"In the past year of this conversation around Bill Cosby's actions against many women, including myself, the most unfortunate thing is the lesson we are teaching children about the worth of a woman's body. I don't know if every woman who has been sexually attacked and comes forward will be one of the many - or one who stands on her own. But as this conversation on Cosby's actions continues, I hope that anyone with kids is thinking of teaching them that no one has the right to another's body or sexuality."
