Monday night's celebrity and professional pairings participated in "Len's Side by Side Challenge" which required each celebrity and his or her partner to dance alongside a female and male professional doing the same exact routine. Both couples attempted to move in sync with one another, and the side by side comparison allowed the judges to see how well the show's stars could measure up to its pros.
Former American Idol finalist and country singer Kellie Pickler and partner Derek Hough finished in second place on the leaderboard with 27 points after they danced a foxtrot routine alongside Anna Trebunskaya and dance troupe member Henry Byalikov.
NFL football player Jacoby Jones and partner Karina Smirnoff finished in third place on Monday night's leaderboard. Jacoby and Karina performed the jive, which earned 26 points from the judges, and were joined by Maksim and Anna.
Fourth place went to 2012 Olympic gold medal winning gymnast Alexandra "Aly" Raisman and partner Mark Ballas after they danced a samba routine that received 25 points. Aly and Mark danced on the stage alongside Tony Dovolani and dance troupe member -- and former So You Think You Can Dancefinalist -- Witney Carson.
The Bachelor star Sean Lowe and partner Peta Murgatroyd finished in fifth place on the leaderboard. Joined by Tristan MacManus and Chelsie, Sean and Peta performed a quickstep routine which earned 24 points from the judges.
Andy and Sharna were joined by dance troupe member Sasha Farber and Emma for their paso doble routine, while D.L. and Cheryl performed the tango alongside Sasha and Chelsie.
The scores of last night's judging leaderboard will now be combined with the home viewer voting results to determine which of the nine couples will be eliminated on Dancing with the Stars' fourth sixteenth-season results show Tuesday night at 9PM ET/PT.
