DANCING WITH THE STARS - "Episode 2105" - Fan engagement through social media has helped to switch up the nine remaining couples. Celebrities and professional dancers switched partners on MONDAY, OCTOBER 12 (8:00-10:01 p.m., ET) on "Dancing with the Stars." Season 18 Mirrorball-winner Maksim Chmerkovskiy guest judged alongside Julianne Hough, Carrie Ann Inaba and Bruno Tonioli. The pressure was on for the pro dancers to choreograph new dances with new partners. Each couple danced to a different style of dance, including the Jive, Cha Cha and Tango. Celebrities will perform one routine with their "switch up" partner and return to their original dance partners the following week. (Photo by Adam Taylor/Walt Disney Television via Getty Images)
