THOMAS COEXGetty Images Being the greatest gymnast of all time and a highly competitive Olympian is no easy feat, mentally and physically—and Simone Biles was forced to pull out of the team finals in Tokyo on Tuesday, citing her mental health. But luckily for Biles, she has a strong support system in her family, namely her parents Nellie and Ronald Biles. The sweet parental pair first made headlines in 2016 when they cheered on their daughter on the sidelines of the Rio Olympics. Due to COVID restrictions they couldn't do the same this year in Japan, but the two remain pillars in Biles's life and career. (Just try not to tear up reading Simone's sweet Instagram posts dedicated to them.) Here's everything we know about Simone Biles's parents, from their unique family story to what they've all said about their relationships with each other.
