And the new pairings aren't the only exciting element of the highly anticipated episode -- DWTS' resident bad boy, 35-year-old Maksim Chmerkovskiy, will return as a guest judge alongside Carrie Ann Inaba, Bruno Tonioli and Julianne Hough.

ET caught up with Chmerkovskiy in May, when he admitted to his own missteps on the hit ABC show.

"I may have come across as angry in some instances in the past," he said candidly. "I've made mistakes. I've reconciled with some people."

"I'm also an entrepreneur and I'm interested in other things," he added about why he decided to leave the show after winning season 18's coveted mirrorball trophy with Olympian Meryl Davis.
