When you think of Simone Biles, her countless accolades as an Olympian likely come to mind. What many might not know, however, is the challenging journey that shaped her into the trailblazer she is today. “Growing up, my biological mom was suffering from drug and alcohol abuse, and she was in and out of jail,” Simone shared in her memoir. After concerned neighbors contacted child protective services, Simone and her siblings entered foster care. Eventually, she and her younger sister Adria were adopted by their grandparents, Ronald and Nellie Biles, while their two older siblings, Ashley and Tevin, were adopted by their great-aunt. Over time, Simone also gained two adopted brothers, completing a unique and resilient family unit.
Simone Biles Siblings
Luckily, Simone’s tough upbringing hasn’t stopped her from finding immense success. And throughout it all, she’s maintained a close bond with her siblings. Here’s everything to know about them.
Adria Biles
Simone and her younger sister Adria, who is also a gymnast, were adopted together from foster care. Despite their unusual circumstances, Adria insists they’re just regular sisters.
“I think when people ask this question, they don’t realize she is completely normal,” Adria told “USA Today” in 2022. “She doesn’t do flips around the house. We still fight sometimes, and I steal her clothes. We are like best friends.”
The two share a striking resemblance and a close-knit bond, often leading people to mistake them for twins.
Ronald Biles Jr.
Ronald Jr., the eldest of Simone’s adopted brothers, is a devoted family man. He and his wife, Samantha, have been open about their struggles with pregnancy loss, infertility, and IVF. Their perseverance paid off when they welcomed their daughter, Ronni Louise Biles, on Nov. 25, 2022. In October 2023, Ronni proudly watched her aunt shine at the World Artistic Gymnastics Championships.
Adam Biles
Simone’s older adopted brother Adam plays a key role in her success. As the general manager of World Champions Centre in Texas—Simone’s training facility—he’s been a constant presence in her journey to greatness. The gym also serves as the training home for 2020 Olympic team silver medalist Jordan Chiles.
Tevin Biles-Thomas
Tevin, Simone’s biological older brother, faced significant legal challenges in 2019 when he was arrested on murder charges related to a triple homicide in Cleveland, Ohio. However, in June 2021, a judge acquitted him of all charges due to insufficient evidence, allowing him to reunite with his family.
Ashley Biles-Thomas
Ashley, seven years older than Simone, has had her own struggles with the law. In 2015, she pled guilty to drug trafficking and has since faced additional legal issues. Despite these challenges, she has shown public support for her younger sister, calling Simone the “G.O.A.T.” in a heartfelt Facebook post.
