"With her determination, she could become a pro at anything. I can see her doing a back walkover in high-heel boots. I know she can do anything. She'll be fine,″ Brumback, 20, said. ″She'll do great, honestly.″ Butler, 22, chimed in and added, ″She's very used to walking in heels already, so I feel like she's a really hard worker. She is a coach and because she did cheer back in the day, I think that she can take good criticism and I feel like she's a hard worker. So I think that she would kill it."
