The cast of "Dancing With the Stars" (5/13/13)
Five remaining couples took to the ballroom floor during the Semi-Finals. Each couple performed two routines, inching their way one step closer to the coveted mirror ball trophy. Last week viewers were asked to vote via twitter on a new style of dance for each couple to perform; this week the couples performed their chosen style, including the Flamenco, Charleston, Afro Jazz, Lindy Hop and Hip Hop. Each couple was also be challenged to take on a ballroom or Latin style dance they have yet to perform this season.
