Black Eyed Peas star will.i.am says the flash mob performance is one he'll never forget. "I hate to sound 'kumbaya' and all deep and whatnot, but it symbolized that we all want to collaborate and come together," he says. "That show, that performance, demonstrated that very concept."
Before he was a guest, will.i.am says he remembers watching The Oprah Show with his mother. "Oprah, thank you for giving my mom something to look forward to all the time," he says. "Thank you so much for the 25 years, and I wish you the best."
