The gossip is that someone on The Cosby Show knows first hand what kind of things happened. Victim.
Speculation has been that it is Lisa Bonet.
Now she tweets this:
According to the karma of past actions, ones destiny unfolds, even though everyone wants to be so lucky Nothing stays in the dark 4ever!

WOW! she tweeted thar? Then she knew what was happening. Remember she suddenly decide to leave the Cosby show to persue a film career or did she leave to get the hell out of there knowing about Cosby.
