The girls were adopted in 2003 by Nellie and Ron Biles and raised in Texas.
Ron is Simone and Adria's grandfather and Shanon's dad, according to CNN.
Simone won four gold medals and a bronze at the Rio Olympics and even got to meet Zac Efron.
Shanon Biles told TMZ that she has been sober since 2007.
