The four finalists on Dancing With the Stars will dance three times during Monday night's performance finale for season 17.

The season 17 cast of 12 celebrities has whittled down to only four remaining:

High School Musical star Corbin Bleu and his partner Karina Smirnoff

Glee actress Amber Riley and her partner Derek Hough

Comedian Bill Engvall and his partner Emma Slater

Reality star Jack Osbourne and his partner Cheryl Burke

The four finalists will first perform a dance chosen by the judges that they have already performed in season 17. They will then dance a salsa relay and finally they will perform a freestyle, in which anything goes.

The two frontrunners based on judges' scores thus far in the season are Amber & Derek and Corbin & Karina. The couples have consistently been fighting for the number one slot on the leaderboard and have only been helped by their previous experiences in dancing.

Amber & Derek will be dancing the Charleston for their Judges' Choice while Corbin & Karina will dance the Quickstep, according to PureDWTS.

Jack & Cheryl have improved significantly throughout the competition, starting off with middling scores at the beginning and gradually improving and getting high-ranking scores. The couple is a dark horse contender to take the trophy from the two frontrunners. They will be dancing the Jive for their Judges' Choice.

Bill & Emma has consistently received low scores through season 17 without any noticeable improvement from the comedian. However, his spirit and good-heartedness have made him popular with the public, who have voted him through all the way to the finals. They will be dancing the Viennese Waltz for their Judges' Choice.
