He Kexin, a Chinese gymnast, won two gold medals during the 2008 Olympics...all the while dealing with speculation that she wasn't allowed to compete. Though her passport stated she was 16 years old at the time of the Olympics, several other registration systems featured a 1994 birthday for her, making her 14 during the Olympics and ineligible. Speaking to reporters after the 2008 Olympic team final, Kexin said, "My real age is 16. I don't care what other people say," and the IOC agreed to leave it at that.
