The all-male finale was set up halfway through the final show when talk show host Ricki Lake was voted off, finishing third. Judges' scores combined with viewer votes determined the winner.

The two-hour finale featured appearances from many of the season's other contestants.

The three finalists each reprised their favorite dance of the season Tuesday to add to their judges' points.

Kardashian and Martinez each had a samba routine to perform before the winner was named.

Kardashian, 24, came into the final episode in first place. He has shown steady development throughout the season, and he and professional partner Cheryl Burke dazzled on the penultimate dance-off with an elegant waltz and a rip-roaring, swing-inspired freestyle routine that judges rewarded with a perfect score.

The two-hour season finale also featured music by Lady Antebellum and appearances by this season's former contestants: TV personalities Nancy Grace and Carson Kressley, reality star Kristin Cavallari, actors David Arquette and Elisabetta Canalis, singer Chynna Phillips, activist Chaz Bono, basketball player Metta World Peace and soccer star Hope Solo.
