Gymnast star Simone Biles has broken the record for the American woman with the most gold medals after scooping a sixth at the World Championships. The talented 17-year-old, from Spring, Texas, won two gold medals on the balance beam and floor on the final day of the annual competition in Nanning, China. They were added to her earlier gold medals in the team and all-around categories, as well as two first-place titles (all-around and floor) in last year's championships  in Antwerp, Belgium. It means that Biles now boasts the most career gold medals from worlds of any U.S. female gymnast, including Shannon Miller, who scooped nine medals overall, five of which were gold.
