China's Ye Shiwen A Swimming Sensation Too Good To Be True? (Video)

China's 16-year old swimming sensation Ye Shiwen is hitting record times as questions are raised whether her performance is too good to be true. Her performance has been no less than miraculous so far. She threatens to overshadow Michael Phelps's bid to become the most decorated Olympian of all time.

On Tuesday, the 16-year old won the gold medal in 200 meter individual medley. On Saturday she took the gold in the 400 meter individual medley -- breaking the world record....and actually swimming faster than men's times in the last 50 meters of the race.

Some say it is too good to be true -- questioning whether doping is involved. China has vehemently rejected suggestions of doping. China briefly dominated women's swimming in the 1990s but their reign ended as fast as it began, following a series of doping scandals that included seven positive tests at the 1994 Asian Games.
