Former "Dancing with the Stars" contestants Melissa Rycroft and Joey Fatone will return to the dance floor this week by performing the tango -- together. It's the first time the show has ever paired up two celebrities.

Pro Mark Ballas will choreograph the number.

Fatone and Rycroft were picked by fans to perform in a contest called Design a Dance. Viewers also chose the dance style, song and costume design.

The two will dance to "Rock and Roll All Nite" by Kiss.

Rycroft is a former Dallas Cowboys cheerleader who appeared as a contestant on "The Bachelor." Fatone was a member of boy band 'N Sync.

The season finale of "Dancing with the Stars" will air May 25.
