Dancing with the Stars: All-Stars' semifinals leaderboard has been topped by Shawn Johnson and professional dance partner Derek Hough.

The Olympic gold medalist gymnast and Hough finished in first place on the judges' leaderboard during Dancing with the Stars' tenth fifteenth-season performance show on ABC Monday night.

Last night's broadcast featured each of the five remaining All-Star couples dancing two individual routines -- one being a dance of an unusual style to a specific theme selected by their fellow contestants, and the other being a routine to one of the songs off Michael Jackson's "Bad" album in celebration of its 25th anniversary.

Johnson and Hough topped the leaderboard after they received a total of 59 out of 60 possible points from Dancing with the Stars' new scoring system, which features 0.5 intervals for the first time in the show's history, for their two dances from Dancing with the Stars judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli.

The couple received a perfect score of 30 out of 30 possible points for their "Night Rider Bhangra" routine, which was an Indian folkdance set to the theme of the television series Knight Rider. They also earned 29 out of 30 possible points for their Argentine tango routine to a Michael Jackson hit.

Reality TV star Melissa Rycroft and partner Tony Dovolani finished in second place on the judges' leaderboard with 57.5 total points.

Rycroft and Dovolani danced a "caveman hustle" which received 27.5 points from the judges and then followed it up with an Argentine tango that earned a perfect score of 30 additional points.

Third place went to Olympic gold medalist speed skater Apolo Anton Ohno and partner Karina Smirnoff. The couple racked in a total of 57 points after earning 27 for their Bigtop jazz routine and then a perfect score of 30 for their subsequent rumba performance.

Fourth place represented a tie between soap star Kelly Monaco and partner Val Chmerkovskiy and NFL football star Emmitt Smith and partner Cheryl Burke after both pairs ended the night with an overall score of 54 points.

Monaco and Chmerkovskiy performed a "surfer flamenco" which received only 25.5 points from the judges, but they managed to raise their total score later on once they danced a rumba routine which earned 28.5 points.

Smith and Burke first took the stage and performed an "espionage Lindy Hop" that earned 27 points from the judges. They then followed it up with a tango routine which received an additional 27 points.

Tonight's Dancing with the Stars: All-Stars results show will feature the elimination of two couples based upon the judges' scores the celebrity and professional pairings had received during Monday night's performance show and the home viewer votes cast afterwards.

Next week, ABC will air Dancing with the Stars: All-Stars finals in which the remaining three couples will perform and then one pairing will be crowned the season's champions.
