Keshia Knight Pulliam knows a lot about what it was like growing up in the spotlight. 25 years ago (yes, it's been that long), she found her way into our living rooms and our hearts as one of the Cosby kids. Now, the nearly 30-year-old actress (her birthday is next month) opens up about what it was like, and how President Obama's girls can stay grounded with all the craziness that surrounds them.

"You can't live for others or worry what people have to say," she tells reporter Chris Yandek. "You just have to be your most true honest you and you'll be fine. People are going to have something to say regardless of how good you do or not. At the end of the day, that's just what it is, their opinion. You can't live your life based on other's opinions."

Pulliam says a normal childhood helped her keep her Hollywood career. "I really loved being able to spend time with my peers and going to regular school," she says. "Like I said, I guess I just had the best of both worlds. I was able to do so much more than anyone else my age or older would've been able to do. I got that interaction with my peers in addition to having a full-fledged career."
