Lisa Bonet Denies Slamming Bill Cosby on Twitter

On Sunday, the blogosphere went into overdrive when a Tweet attributed to Lisa Bonet seemed aimed at Bill Cosby.

'According to the karma of past actions, one's destiny unfolds, even though everyone wants to be so lucky,' read the Tweet, which was posted on an account using Bonet's name. 'Nothing stays in the dark 4ever!'

Was Bonet - who played Cosby's daughter, Denise, on The Cosby Show from 1989 to 1992 - addressing the numerous sexual assault allegations against the 77-year-old comedian? (The actor has denied the claims through his lawyer.)

The answer: No, she was not.

'Lisa Bonet has no social media of any kind,' her manager tells PEOPLE exclusively.

'Any posts made in her name were made by impersonators with unverified accounts. She also has no comment on the ongoing story.'

The fake Twitter account has since been suspended.

Bonet isn't the first of Cosby's Huxtable family to speak out. Raven-Symoné (who played Cosby's step-granddaughter, Olivia, on the show) took to social media last week to deny rumors that she was one of his victims.

'I was NOT taking advantage of by Mr. Cosby when I was on the Cosby Show!' she posted on her Instagram. '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!'
