The competition is closer than ever as the four remaining pairs perform three pressure packed routines -- one ballroom and one Latin dance they've not yet done, and one winner-takes-all Cha Cha -- for the chance to make it to the Season 12 finals.

On Tuesday, a fourth couple will be eliminated from the competition and special musical guest country star Toby Keith performs two of his biggest hits. In a moving tribute to his country and U.S. Troops overseas, the Grammy-nominated artist will sing "American Soldier," accompanied by "Dancing with the Stars" pros Anna Trebunskaya and Jonathan Roberts, and "Should've Been a Cowboy" with Maks Chmerkovskiy, Lacey Schwimmer and the "Dancing with the Stars" Dance Troupe. This week's "Macy's Stars of Dance" American week performance is a powerful number choreographed by Jamal Sims.

"Dancing with the Stars" has its first-ever classical themed week, as the show's nine couples try to outshine one another on the dance floor performing to traditional and modern classical music from world renowned musicians. Conducted by "Dancing with the Stars" band leader Harold Wheeler, a full 46-piece orchestra will be joined by multi-platinum mezzo soprano Katherine Jenkins and international violin virtuoso David Garrett.

The competition grows tougher as a second couple is sent home.
