Lisa Bonet prefers to "plead the fifth" when it comes to talking about the sexual assault allegations involving her former on-screen father, Bill Cosby.
According to her daughter Zoe Kravitz, the 47-year-old former "Cosby Show" star doesn't even speak about the scandal with her own family.
While her mother remains tight-lipped about the allegations against Cosby, Kravitz insists that if Bonet knew something, she would say something.
"She's a very straightforward person," Kravitz said. "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."
Over 46 women have alleged that 78-year-old comedian sexually assaulted them, including former "Cosby Show" actress, Eden Tirl. Cosby has denied all accusations regarding sexual abuse and has never been criminally charged.
One of his accusers, former model Beth Ferrier, spoke with ET about her alleged encounter with the comedian in the '80s. Ferrier claims Cosby drugged her when she went to visit him in Denver by slipping something into her cappuccino.
"I thought he cared and loved me," Ferrier said. "He drugged me and that was it."
