Simone Biles
Simone Biles and her sister, Adria, had a tough time growing up. "My biological mom was suffering from drug and alcohol abuse and she was in and out of jail," Biles revealed on a TV show. At the age of three, Biles' maternal grandparents stepped up to the plate to care for the children. Ron and Nellie Biles raised the kids in Texas and legally adopted their grandchildren as their own in 2003.
