Musical Performers Include Season 17 Champion Amber Riley, Christina Perri, Iggy Azalea featuring Charli XCX, Cody Simpson and Ariana Grande

"Episode 1810 & 1810A" - After nine weeks of competitive dancing spanning a variety of styles from the Cha Cha to the Foxtrot to the Viennese Waltz and beyond, Amy Purdy & Derek Hough, Meryl Davis & Maksim Chmerkovskiy, Candace Cameron Bure & Mark Ballas, and James Maslow & Peta Murgatroyd remain in the competition, but only one couple will be crowned "Dancing With The Stars" champion. These four remaining couples will have one last opportunity to impress the judges and the viewers on MONDAY, MAY 19 (8:00-9:30 p.m., ET), concluding with the Season Finale, TUESDAY, MAY 20 (9:00-11:00 p.m., ET) on the ABC Television Network.

On MONDAY, MAY 19 (8:00-9:30 p.m., ET), the four remaining couples will compete in two rounds of dance. In the first round, each couple will take on the "Judges Pick" and repeat the same dance style they did the week of the "Switch-Up." In the second round, one of the biggest competitive dances of the season, the couples take on a supersized Freestyle featuring special effects, additional dancers and unexpected surprises. At the end of night, one couple will be eliminated based on the previous weeks' viewer votes, combined with the judges' scores from the previous Monday night.

In the two-hour Season Finale on TUESDAY, MAY 20 (9:00-11:00 p.m., ET) the show will begin with a high-energy performance featuring a reunion of all 12 of this season's couples as well as the judges. Then, as decided on by a Twitter vote, one of the three remaining couples will perform their Freestyle dance as an encore. The finale will also feature a performance to "Livin' La Vida Loca," by Team Loca, giving viewers at home a chance to watch the routine live with Amy Purdy, as she was unable to dance during the original Team Night due to an injury. Additionally, viewers will be treated to encore performances by Drew Carey and Cheryl Burke to "You Can't Sit Down," NeNe Leakes to "Grown Woman" featuring six Pro Dancers, Danica McKellar and Val Chmerkovskiy to "Be Our Guest," and Charlie White and Sharna Burgess to "Supercalifragilisticexpialidocious." Additionally, Olympic Gold Medalist partners Charlie and Meryl will dance together for the first time. In the last element of competition, the couples will perform a new routine as part of a "24 Hour Fusion Challenge." The remaining couples will fuse two contrasting dance styles that they've performed this season and they'll have less than 24 hours to prepare that dance for judges' points.

Last season's Mirrorball Trophy winner, Amber Riley, will return as a part of Walgreens' "Dance Happy Be Healthy" performance of "Do Your Thing" plus her first single "Colorblind." The finale will also feature musical performances by Christina Perri singing her ballad "Human," Iggy Azalea featuring Charli XCX will perform their hit "Fancy," Season 18 contestant Cody Simpson will treat fans to his hit "Surfboard" and Ariana Grande will perform her new single "Problem." At the end of the night, the public vote from Monday night will be combined with the judges' scores from both nights to crown the Season 18 Champion.
