The mature routine was a far cry from the 16-year-old gold medalist’s adorable, bubbly public persona
, and Hernandez told ET after backstage that her costuming gave her the confidence she really needed.
"It was really hard but the outfit and the makeup really helped," Hernandez shared with ET's Angelique Jackson after the show. "They were doing my makeup and they did a dark lip and they straightened my hair and I was like, 'Oh, this is very sassy! Well, we're doing the tango!'"
Between DWTS, publicity engagements and performing with the other members of the Olympic Final Five on the Kellogg's Tour of Gymnastics Champions, Hernandez has a full plate. However, she says she's managing to balance it all by "remembering my passion for dancing."
"[I] never even want the chance of going home because I love dancing," she said. "I love doing Dancing With the Stars, and I've always loved this show, so I'm just glad I get another week to do what I love."
Hernandez dished on the adorable moment, which was captured on video and shared to Instagram, telling ET, "I lost all chill. I was so embarrassed."
"Any chill I had built up in the past 16 years has just left. Oh my god!" Hernandez said. "She added me back on Snapchat so I think we're kinda friends now."
