Just 19 years old, Simone Biles is the favorite to win the women's world gymnastics all-around title and is considered a strong contender to win five gold medals in all. She was the first African-American female to win the all-around title with her win in 2013. In addition, she's the first woman to win three consecutive world all-around titles. Her 10 world gold medals is the most by any female gymnast in history.
Now, she's seeking Olympic gold in Rio in her inaugural Games.
The gymnast was born in Columbus, Ohio in 1997, but her hometown is Spring, Texas. She discovered gymnastics through a day care center field trip and started competing at age seven.
Biles has three siblings: Ronald II, Adam and Adria. Simone and her sister Adria, who is also involved in gymnastics, were raised by their grandparents Ron and Nellie, because of their mother Shanon's struggle with substance abuse. The two girls were officially adopted by their grandparents when Simone was six.
