Check out Chelsea Kane and her pro partner Mark Ballas in these official cast photos for Dancing with the Stars!

Earlier this week, the 21-year-old actress was spotted heading to a dance studio for rehearsals.

Seems like Chelsea is already feeling the pain from all the training!

“My feet are not my friends,” she tweeted.

Mark, meanwhile, tweeted that he taught Chelsea the foxtrot, which they’ll be performing on the season premiere on March 21!
