Monday's episode of ABC's "Dancing with the Stars" will be a two-hour special that will see all four couples doing their individual routines, as well as a dance-off segment.

Last week saw the elimination of Alexa PenaVega, and one day later Tamara Braxton withdrew from the competition citing medical reasons.

The show is now left with four celebrity dancers —Nick Carter, Bindi Irwin, Alek Skarlatos and Carlos PenaVega -- and all four of them will dance their way to the finals, as there won't be an elimination segment on Monday.

Here are the dances for Monday night:

Individual

Alek Skarlatos and Lindsay Arnold — Waltz to "America The Beautiful"
Bindi Irwin and Derek Hough — Salsa to "You're Never Fully Dressed Without a Smile" by Sia
Carlos PenaVega and Witney Carson — Contemporary to "Drag Me Down" by One Direction
Nick Carter and Sharna Burgess — Tango to "Scars" by Alesso feat. Ryan Tedder

Trio

Alek Skarlatos and Lindsay Arnold and Emma Slater — Argentine Tango
Bindi Irwin and Derek Hough and Mark Ballas — Jazz
Carlos PenaVega and Witney Carson and Karina Smirnoff — Samba
Nick Carter and Sharna Burgess and Peta Murgatroyd — Salsa

The final performances will be the dance-off between the four celebrity dancers. Carter and Burgess will go against Irwin and Hough, and the other two celebrities and their partners will face-off each other.

So who will win the finale? According to bets on Gold Derby, Carter and Irwin seem to be the favourites to win the Mirrorball trophy. PenaVega and Skarlatos come in the third and fourth positions.

One of the reasons why fans believe Irwin will win the current season of "Dancing with the Stars" is because she is paired with Hough, who has won the dancing reality show five times in the past.

"Dancing with the Stars" semifinals will be aired at 8 p.m. ET on Monday. Click here to watch the episode online.
