Lisa Bonet, the ex-wife of rock artist and Hunger Games actor Lenny Kravitz, denied slamming Bill Cosby on Twitter.

Fifteen women, including Florida nurse Therese Serignese, "Incredible Hulk" star Lou Ferrigno's wife Carla Ferrigno and Michelle Hurd, from "Law & Order: Special Victims Unit" and the model Janice Dickinson, have come forward to accuse Bill Cosby, 77, of allegedly drugging and raping them.

According to reports, Lisa Bonet took to Twitter with a cryptic tweet aimed at Cosby on an unverified Twitter account that had been set up in Bonet's name.

The Twitter post that was attributed to Lisa Bonet read: "According to the karma of past actions, one's destiny unfolds, even though everyone wants to be so lucky . . . Nothing stays in the dark 4ever!"

The tweet was reported to appear to be a comment about the sexual misconduct allegations surrounding Bill Cosby, but the actress' manager said it was a hoax.

In a public statement, Lisa Bonet's manager refuted the actress' remarks about Bill Cosby. Bonet's manager said the actress has no official social networks and that the Twitter comment came from a fake account that has since been deleted.

Speaking to The Wrap on Sunday, talent manager Jillian Neal said "I can assure you that is not her Twitter account and I have had the account suspended."

Bonet's manager said the actress was not responsible for the account or the tweets, telling People.com "Lisa Bonet has no social media of any kind. Any posts made in her name were made by impersonators with unverified accounts. She also has no comment on the ongoing story."

Raven Symone auditioned for a role in the hit 1990 Sidney Poitier-directed film, Ghost Dad which starred Bill Cosby in the lead role. Even though Raven was considered too young for the part, Bill Cosby decided to bring her on-board The Cosby Show as his step-granddaughter Olivia.

Raven-Symone also recently denied rumors that she was one of his alleged victims.

"I was NOT taking advantage of by Mr. Cosby when I was on the 'Cosby Show'! I was practically a baby on that show and this is truly a disgusting rumor that I want no part of! Everyone on that show treated me with nothing but kindness. Now keep me out of this!" Raven-Simone posted on Instagram.

In a statement, Cosby's attorney, Marty Singer, called Dickins's claims an "outrageous defamatory lie."
