US Olympic swimmer AMANDA BEARD has ended her year-long romance with US racing car driver CARL EDWARDS, insisting her ex-boyfriend's sport was "too intense" for her. The seven-time Olympic medallist, who was voted the World's Sexiest Athlete in men's magazine FHM recently, explains she's too laid-back to date a high-octane Nascar racer. She says, "I'm a surfer girl from California, and when you date a race-car driver, there's so much stress."
