They're not exactly strict in policing that. I mean, they let Heather Morris on the show, and she was literally a professional dancer.As a side note, why do they let ice dancers on DWTS? Like literally it's not much different. I'm sure ice dancers practice by doing their dances on the floor. And there is significant overlap in the dances. If the Shibutanis did DWTS, I'm almost sure one of them would win.
