Sir Paul McCartney tried to keep his international fame from his daughter STELLA - but the clever youngster figured out his identity on her own. The fashion designer - who is the daughter of the ex-Beatle and his late wife Linda - was kept unaware of her father's career for years, but the star, now 36, eventually managed to solve the secret of his worldwide celebrity. He says, "There was this one moment where the children were riding their little ponies in Scotland, and Stella said to me, 'Dad, you're Paul MCCartney, aren't you?' and I said, 'Yes, darling, but I'm Daddy really.'"
