Who Is Simone Biles’ Sister?

Simone Biles is dazzling the crowd in Paris-Bercy with her jaw-dropping floor routines, and if you spot someone in the stands who looks like she could be Simone’s twin, you’re not seeing double. That’s her sister, Adria Biles! These two are two peas in a pod, yet Simone’s not just an older sister; she’s a second mom to Adria. Over the years, Adria has been Simone’s loudest cheerleader from the stands, though the pandemic in 2021 had her cheering from afar during Simone’s Tokyo “Twisties.”

But now, as Simone makes her epic comeback, Adria is right there in the action. Remember that heartwarming moment when Adria was caught on camera in the Target Center, wiping away tears of joy and posting, “See you in Paris, sissyyyy 🤩 @SimoneBiles” Well, she’s back now at the Paris Olympics to fulfill that promise. And here’s a fun nugget: Adria’s not just a supportive sister; she’s a gymnast herself! Who knew the Biles family had double the talent?

Meet Simone Biles’ lookalike sister, Adria Biles

Simone Biles and her lookalike sister, Adria Biles, could totally pass for twins if it weren’t for their six-inch height difference! Adria, standing at 5-foot-2, joked to People, “I’m a good head taller than her. When we’re side by side, people can definitely tell us apart.” Even when Simone first stole the spotlight at the Rio Olympics, Adria was frequently mistaken for her, with fans in Brazil asking for autographs and selfies. Growing up, the sisters were inseparable, turning their second-floor railing into a balance beam and leaping onto the couch below—a fearless tradition that highlighted their shared love for gymnastics. But their bond goes way deeper than their shared love for gymnastics.

Simone and Adria spent three years in the foster care system after being removed from their biological mother’s care due to addiction issues. Their maternal grandparents, Ronald and Nellie Biles, took them in, providing a loving home and stability. They eventually adopted the sisters as their own. From a young age, Simone, who is only a few years older, became a motherly figure to Adria, feeling a strong sense of responsibility to look out for her sister.

Adria competed as an elite gymnast for a decade. After her gymnastics career, she joined the Houston Astros’ professional dance team, the Shooting Stars, where she not only dances but also represents the team in community outreach and charity events. In June 2024, Adria and Simone appeared together in a fun U.S. Bank commercial, where they shop for everything from clothes to a massage chair.

Adria even made a splash on TV with her stint on Claim to Fame, where she played under the pseudonym “Louise” but was eliminated midway. Despite the fame, Adria says her sister is “completely normal” and adds, “We still fight sometimes and I steal her clothes. We are like best friends.” But why did she not continue to pursue the sport like her sister?

Adria Biles followed the footsteps of her big sister

Adria Biles followed in her big sister Simone’s footsteps by starting gymnastics at age 9, quickly advancing to the Level 10 stage by 2016, around the age of 17. Growing up, the Biles sisters were inseparable, often using a second-floor railing as a makeshift balance beam before leaping onto the couch below—a fearless tradition that showcased their shared passion for gymnastics. “She’d go first, and I’d follow,” Adria once reminisced. Adria competed as an elite gymnast for a decade but decided to step back from the sport in 2016, just as Simone was making Olympic history. Despite her impressive career, Adria hung up her leotard that year. Why did she decide to move on?

Well, as Simone once pointed out, the relentless comparisons and pressure were a bit too much for Adria. Simone shared, “Whenever she went to competitions like ‘Oh, her sister always wins, she always wins, that’s not fair.’ So she quit.” Despite her exit from the sport, Simone still teases Adria about making a comeback. In 2021, Simone jokingly retweeted a study saying younger siblings often do better in the same sport and tagged Adria with a playful, “uh oh @adria_biles you better get back in the gym.” Adria’s response? “Nahh that’s all you, sister,” adding, “Not the case in this case.”

Even though Adria isn’t flipping on the mat anymore, she remains Simone’s biggest cheerleader—sometimes even popping up at WCC, the gym owned by their parents where Simone trains, just to stay connected to the sport.
