22-year-old Simone counts 15 gold medals in her collection of 21 World Championship accolades, and she also holds 5 Olympic medals, 4 gold, and 1 bronze.
Simone's 21st medal was awarded to Team USA for the Women's Team Final event, but that may not be the last medal she takes home this year.
So far, Simone has been dazzling the audience and the judges and has introduced two new moves, which will be named after her. The odds in the individual competitions look good.
