Maureen McCormick and Artem Chigvintsev
Despite her nerves and an injury, Maureen McCormick has been improving in the ballroom. She previously talked about her injury to E!: It's been one of the most painful things I've ever had happen to me, I think maybe the most. ‘Cause every time we've had a rehearsal, we've had to stop and it's like bone-to-bone, it's like a knife, just going all over ... I couldn't do the steps, so we had to go visit doctors, we spent the night at Cedars Sinai ... but we did it. (Instagram)
