Seeing Double: The Cutest Pictures of Simone Biles and Her Sister Adria

Simone Biles and her sister Adria are two peas in a pod. The latter is currently appearing on the ABC reality competition series "Claim to Fame," attempting to hide her identity from a group of other contestants with famous relatives. As soon as Adria appeared on screen to introduce herself as "Louise," her resemblance to Simone was evident to both viewers at home and this season's competitors, despite valiant attempts to throw everyone off.

At 23 years old, Adria is two years younger than her Olympic gymnast sister. They also have two older biological siblings: a sister named Ashley and a brother named Tevin. Simone and Adria were adopted by their grandparents, Ron and Nellie, at a young age and grew up together in Houston, forming an incredibly close bond. Adria followed in Simone's footsteps and competed in gymnastics at the junior elite level as a teen, but these days, she's a member of the Houston Astros Shooting Stars dance team.

A quick scroll through their social media pages reveals Adria and Simone's undeniable love and support for one another. Pinned at the top of Adria's Twitter is a 2019 tweet that reads, "my sister is amazing. that's it. that's the tweet." Plus, last summer when Simone withdrew from several Tokyo Olympics competitions as she grappled with a mental block that gymnasts call "the twisties," Adria stood up for her sister's decision. At the time, Adria tweeted, "y'all are all about mental health until it no longer benefits you.. i can't imagine being that inconsiderate WHEWWWW." Simone similarly showers her baby sis with with affection, always sharing sweet Instagram tributes for Adria's birthday and holidays like National Sibling Day.
