The second night of the Dancing With the Stars season finale was jam packed with guest musicians. As the crowd waited to find out who would take home the mirror ball trophy, they were regaled with the stylings of Psy.

The South Korean rapper rose to international fame last year with his viral video for "Gangnam Style" which came form his sixth studio album. With over 1,600,000,000 views, the video became the most viewed YouTube upload of all time. In April, the 35-year-old released his follow up single "Gentleman" which was paired with another dance-centric video. "Gentleman" quickly found similar online success.

With his "Gangnam Style" dance just as popular as the song, it was a natural choice for the show to invite the prominent rapper to perform.

Psy took the stage with four female dancers and quickly launched into "Gentleman." Following the dance moves from the video, Psy quickly had a whole host of dancers on the floor with him as green laser lights flashed in the background. The crowed cheered throughout the performance, waving glow sticks and donning flashing glasses.

As confetti rained down on the performers near the end of the routine, Psy headed over to the judges table and brought Len Goodman, Bruno Tonioli, and Carrie Ann Inaba in on the fun to close out the performance.
