The latest woman accusing Bill Cosby of drugging and assaulting her says she was knocked out for two days after he invited her to his hotel room to run lines in 1988.

The woman, who identified herself only as "Lisa," appeared on Dr. Phil in an interview set to air Friday. She told the TV doctor she was 21 when she met Cosby, who offered to help her with her career.

The first time they met, "He was a gentleman and he was respectful and kind and he seemed very interested in me and that made me feel very secure in seeing him again. He was the Jello pudding man, he was everyone's dad," Lisa said.

Cosby later met her mother and sister, who were both won over by the charismatic actor. "My mother trusted Bill completely," Lisa says in the teaser clip.

But not long after, Lisa says, he summoned her to his hotel room "out of the blue."

He talked about, "Let me see what type of acting skills you have, I want you to improv." And as I tried to do improv, he fixed a drink and then he brought it to me. It was a brown liquid and it looked like a shot. I told him I didn't drink. He said that this was going to relax me so that the lines would flow out a lot easier. So I had to drink it. He made a second drink and had me drink the second drink as well.

I noticed myself getting a little dizzy. Bill had sat down on the edge of the couch. He said, "Come over here and have a seat." He had his legs open and when I sat down, I was sitting down in between his legs with my back to his crotch. He started to stroke my hair back in a petting motion, like this. The last things I remember is just feeling the strokes on my head. After that I don't remember anything else.

According to the Daily Mail, she woke up two days later in her own bed.

Lisa told Dr. Phil she wanted to report the assault at the time to "let him know that I know he did something wrong," but didn't because she feared testifying about events she couldn't remember.
