Another woman has come forward with claims that she was allegedly raped by comedian Bill Cosby. Katherine McKee, now 65, told the New York Daily News that Cosby raped her during the late 1970s.

McKee, who was a Las Vegas showgirl and Sammy Davis Jr.'s mistress, said that she often traveled with Davis and his notorious Rat Pack. Through Davis, she became friends with Cosby and even appeared on an episode of "The Cosby Show" in 1971 before the alleged attack.

"Back then, I was Sammy's road wife. He had an open marriage, and we were lovers. That's how it went," she said.

McKee explained that one night Cosby invited her to a boat party in Detroit but before the two made it to the event, the comedian allegedly attacked her. She told the publication that Cosby had asked her to pick up some ribs for the party and then meet him at his hotel room.   

"He was a buddy. He knew I was Sammy's girl," she said about why she accepted Cosby's invitation to the party.

"I remember I walked in the door, and he had a robe and cap on. He took the ribs from my hands and just grabbed me," she said. "He spun me around, pulled my panties down, and just took it. We were still standing at the door when he attacked me. It was so fast and so shocking and so unbelievable."

"To me, there was a different personality involved," McKee added. "He was a different man. It felt like a different person performing that act."

McKee said she ran to the bathroom to compose herself while Cosby got dressed. The two rode the elevator to the party in silence.

"I never said a word. I was too uncomfortable about it," she told the Daily News. "Bill was so rude and cold toward me the rest of the night. I thought, 'When this boat docks, I'm out of here.' I just left."

McKee said she never told Davis about the alleged attack and she didn't utter a word about it, until now.

"I was mad at my own self for not saying, 'What the f--k?' Why didn't I stop it and get him away from me?' But it happened too fast. I was absolutely flabbergasted," she said.
