LOL well the news sites have already latched onto to Corbin and Elizabeth, calling them trained dancers and saying that they have an unfair advantage over the others.
I'm not sure because I think the popularity of Bill, Jack, Valerie and some of the others may trump their prior training.
Disney produces/owns this show, right? So maybe they wanted to finally get themselves a win by getting a trained dancer from one of their most popular shows? I don't know. I'm just feeling a bit cynical about these two, maybe.
