One of the music industry's biggest mysteries revolves around Carly and her 1973 Billboard hit song, "You're So Vain." For decades fans have wondered who the song was written about—but Carly's lips are sealed. In fact, the only media member she has told her well-kept secret to is Dick Ebersol, an NBC executive who won a $50,000 auction to hear her muse's name. Oprah says now might be a good time to name names, but Carly just smiles. "Nice try, there," says Carly's daughter, Sally.
