ABC has announced details on the two-part finale episode of Dancing With the Stars Season 18, and it looks to be jam-packed with musical performances and repeat dances.

Among the stars set to sing during the two-hour finale episode Tuesday are Ariana Grande, Iggy Azalea, Charli XCX, Christina Perri, and one of the season's competing celebrities, Cody Simpson. Grande will perform her new smash hit single Problem while Azalea will also perform her hit, Fancy, with Charli XCX. Perri will perform her song Human while Simpson will perform Surfboard.

Meryl Davis In Danger Of Elimination on DWTS Despite Frontrunner Status?

Additionally, the finale will include a repeat of the Livin' La Vida Loca dance from Team Loca. This is due to the fact that contestant Amy Purdy was unable to dance live the night they performed the group dance.

Many of the show's standout dancers are coming back to reprise various dances for the finale.

Also, current contestant Meryl Davis and recently-cut contestant Charlie White will be dancing together for the first time. Davis and White are Olympic Gold Medalist partners.

The last portion of the competition will feature the three remaining couples dancing in the 24 Hour Fusion Challenge. This gives the contestants only 24 hours to fuse two dances together with their partners. This dance will be the final dance scored in the competition.

Dancing With the Stars Season 18 will air its two-part finale Monday and Tuesday on ABC.
