Dancing with the Stars returned for week 5 with the Switch Up (original airdate October 12, 2015), where celebrities switched Pro partners based on fan votes. Former DWTS pro and Season 18 champion Maksim Chmerkovskiy took a seat at the judge's table alongside Julianne Hough, Carrie Ann Inaba and Bruno Tonioli to weigh in on the new pairs. Lindsay Arnold helped Carlos PenaVega come roaring back into the competition with strong Quickstep that earned 10s from three of the judges. Not to be outdone, his wife Alexa PenaVega and new partner Derek Hough earned the first perfect score of the season with a fierce Tango. Bindi Irwin kept everyone smiling with an energetic Cha Cha with Val Chmerkovskiy earning an impressive 10 from Maksim.
