Cheryl's partner, former wrestling star Chris Jericho, explains that even for a tough guy like him, wearing those flashy outfits was not a problem: "It's funny, because people say to me, 'What do you think of those costumes?' I'm like, I've been wearing spandex with rhinestones and sparkles for 20 years! You can't shock me - I want more!"
