"Dancing with the Stars" season 20 has picked the final three pairs to grace the epic dance battle for the golden MirrorBall Trophy. The couples will have to dazzle the viewers and judges one last time before the wildly popular celebrity dance competition determines the latest conqueror of the dance floor. 

The pairs will perform three times. The first presentation will be a reprisal of a routine they performed earlier in the season to show the judges and viewers that they are primed to outshine not only their competitors but themselves and prove how much they've grown throughout the show. 

The following routine will be freestyle. The third performance, which will happen on Tuesday, is the 24-hour fusion challenge, which will allow the contenders to earn more points from Julianne Hough, Len Goodman, Bruno Tonioli, and Carrie Ann Inaba. 

Noah Galloway and Sharna Burgess will make an encore performance of the Latin Night Argentine Tango they executed back in Week 3. The pair will also perform a Contemporary piece. 

Rumer Willis and Val Chmerkovskiy will perform Foxtrot, which they performed in the show's first week. This will be followed with an Argentine Tango intermingled with a contemporary touch as their freestyle performance for the night. 

Lastly, Riker Lynch and Allison Holker will recreate their iconic "Pirates of the Caribbean"-inspired routine, which they performed on Disney's Night. This netted the pair two perfect scores and two near-perfect scores. The couple seems to be aiming four 10s with this. 

A flurry of stars will grace the party before "Dancing with the Stars" season 20 crowns its winner. Previous contestants from this season will take the stage once more. "DWTS" alums such as last year's Sadie Robertson and Alfonso Ribiero will join the revelry as well as Amy Purdy. 

Fifth Harmony will sing their dance-y new single "Worth It" while Redfoo is all fired up for a concert party by performing "Juicy Wiggle." Patti LaBelle, who was a season 20 contestant, will belt out some tunes with her song "2 Steps Away." 

Jason Derulo will continue the festivity by performing his latest hit "Want to Want Me" while Derek and Julianne Hough will show off their dance moves as they dance to "Elastic Heart," which will be performed by Sia on the show.

The "Dancing with the Stars" season 20 finals will air tomorrow, May 18, and on Tuesday, May 19.
