Hernandez, 16, will reportedly be up against fellow Olympian Ryan Lochte, The Fosters alum Jake T. Austin, Brady Bunch star Maureen McCormick, social media and TV personality Amber Rose, R&B singer Kenneth "Babyface" Edmonds, General Hospital star Emma Samms and Little Women: LA star Terra Jole. Derek and Julianne Hough are also set to return as a dancer and judge, respectively, along with dancer Maksim Chmerkovsky.
Hernandez has some big shoes to fill when she takes her skills to the dance floor. The last Olympic gymnast who competed on Dancing, Shawn Johnson, went on to win the Mirror Ball trophy in Season 8. When Johnson returned in 2012 for an all-star season, she placed second behind Melissa Rycroft.
The full Dancing with the Stars cast will be announced on Good Morning America on Tuesday. Dancing with the Stars returns Monday, Sept. 12 at 8/7c on ABC.
