Dancing With the Stars 2013 heads into the semifinals tonight, and for Season 16: Week 9, Ingo Rademacher and Kym Johnson danced the Charleston for their Round 2, Twitter-chosen performance. It was fun and inspired, and it definitely excited the judges. “Ingo, you had a grand slam with that one!” Carrie Ann exclaimed. “Like champagne, it was bubbly and full of fizz. The semifinals — good time to do your best dance,” Len added. It was no surprise that they scored 27/30!
