Lisa Bonet is said to be “disgusted” by Bill Cosby’s rape allegations, but is not likely to openly speak about it anytime soon.

According to UK’s The Guardian, Bonet’s daughter, Zoe Kravitz, says The Cosby Show alum wants to keep her opinion to herself, but she’s said to be upset about allegations that Bill Cosby sexually assaulted more than 40 victims.

When asked whether Lisa Bonet, 47, had discussed the allegations with her, the Mad Max: Fury Road star, 26, said her mother likes to keep her opinion to herself.

“She hasn’t, she really hasn’t. She’d plead the fifth, even to me. I think she’s just staying out of it,” said Kravitz, whose father is rocker Lenny Kravitz. “She’s just as disgusted and concerned as everyone else is, but I don’t think she has any insight. It’s news to her as well.”

Bonet, who starred on The Cosby Show from 1984 to 1991, playing Denise Huxtable (later Denise Kendall), the second-eldest daughter of Cliff (Cosby) and Clair (Phylicia Rashad), was just 17 when she started the series and left when she was 23.

“She was on the show for a long time. She’s also a beautiful woman. It makes people wonder,” said Kravitz. “She’s a very straightforward person. If there was something she felt the world needed to know that would help this case or help any women who had been abused, she would say something.”

Cosby is accused of sexually assault several dozen women, many of whom claim the comedian drugged and raped them in the 1960s, ’70s, and ’80s.

Us Weekly reported in July that court documents obtained by the Associated Press indicate that Cosby admitted to getting quaaludes with the intent of giving them to women he wanted to have sex with, but the actor’s lawyer has said people are “misinterpreting” his words.

“I’m not making conclusions — and you know that I can’t — about whether someone is lying or not,” attorney Monique Pressley told Good Morning America in July. “What I am saying is that Mr. Cosby has denied the accusations that have been lodged thus far. The sheer volume or number of people who are saying a particular thing does not make it true.”
