    Age difference: 16 years

    When teenage pop star Billie Piper appeared on media mogul Chris Evans' radio show in December, 2000, she had no idea she was being introduced to her future husband. The DJ, 16 years older than the singer, wooed her by buying her a rose-filled Ferrari, even though she had yet to pass her driving test. After a whirlwind romance and rumours the whole thing was a publicity stunt the two wed in Las Vegas on May 6, 2001. "The age difference doesn't bother us in the slightest," says Chris. "She's a lot older and wiser than her years and I'm a lot younger, so we kind of meet in the middle and it works." He adds: "She has a very old head on a lovely body."
