Are you ready to be entertained? The remaining three couples on “Dancing with the Stars” will pull out all the stops on Monday night's episode with the hopes of impressing both the judges and fans one last time before the Season 20 finale. And we’ve got the scoop on what viewers of the hit ABC series should anticipate from the contestants who are each fighting for the title of "DWTS" victor and ownership of the coveted Mirror Ball Trophy.

According to the synopsis for Monday’s hour-long installment, the final three couples (Noah Galloway and Sharna Burgess, Riker Lynch and Allison Holker, and Rumer Willis and Valentine Chmerkovskiy) will be performing two dances during the second to last episode of the 2015 season.

“The three finalists will compete in two rounds of dance,” the summary reveals, adding that in the first round of the upcoming installment “each couple will repeat a dance from earlier this season.” What routines do you think the couples will perform? Well, from past scores, we theorize it's safe to assume the remaining duos will each reprise their best scored dances from Season 20. Noah and Sharna earned a 40 for their fiery Paso Doble during the Week 9 “Semifinals,” while Riker and Allison received perfects scores for their Contemporary routine and their Argentine Tango during the last installment. Rumer and Val have the most options to choose from seeing as though they earned perfect scores for their Rumba, Paso Doble and Contemporary performances throughout the season.

“In the second round, in one of the biggest competitive dances of the season, the couples take on a supersized Freestyle dance featuring special effects, additional dancers and unexpected surprises,” the synopsis explains of what audiences can expect next during Monday night’s episode.

It was previously revealed that Rumer and Val will be rocking the ballroom floor to a cover of Britney Spears’ sexy single “Toxic” during their Freestyle number. And according to reports, Rumer will be the one belting out the chart-topping tune while Val adds flare via the violin.

Val recently shared a photo of him and his partner working on the rendition of the song in the studio, stating that he was excited for fans to hear it in the forthcoming installment. “Tune in to @dancingabc Monday night 3DWTS #TeamValenRue,” the musician captioned the Instagram picture. It was reported that the song will be made available on iTunes after the episode airs.

Rumer won’t be the only one breaking out in song during the live episode. Us Weekly revealed that the girl group Fifth Harmony, who presented during the 2015 Billboard Awards on Sunday night, will perform their hit song “Worth It” on “DWTS” Monday. As Camila Cabello, Lauren Jauregui, Ally Brooke, Dinah-Jane Hansen, and Normani Hamilton serenade the crowd with the foot-tapping, rhythmic single, the female dancers of “DWTS” will shake it to the jazzy beat featuring Kid Ink.

Tune in to Season 20's Week 10 of “Dancing with the Stars” on Monday, May 18, at 8 p.m. EDT on ABC.
