Oprah had a "retro party" on her show yesterday, and as part of that, she recreated the set of The Cosby Show and reunited the kids. (Except for Lisa Bonet, who was unable to attend because she just had a baby.) They all talked about how they weren't aware until they were older what an impact the show had on society and gave a little insight into why they didn't fall into the child star trap. The biggest news though is that Rudy, aka Keshia Knight Pulliam, grew up to be way hot. Clip above.
