"I've been a pro dancer on the show for about seven years now and am eager to explore other opportunities that have been made possible because of Dancing with the Stars. I'm going to take this time to dive into producing and acting, while fulfilling my sponsorship obligations. A big thank you to all of my fans for your never-ending support. I also want to thank the entire cast and production of Dancing with the Stars."
Chmerkovskiy -- who has competed in thirteen of Dancing with the Stars' prior seasons but never won -- had previously announced he planned to leave the show when his contract expired after Season 17.
"This has been such a big part of [Maksim's] life and such a big part of our family's life the last seven years," Val told People. "It's obviously sad to see him not be a part of it, but it's an open-ended finish. My brother and Dancing with the Stars have a very good relationship. For the fact that they're allowing him to do his thing and discover his other talents and passions and acting, I'm happy. Everybody's happy, everybody's positive."
"We frequently rotate the professional dancers, so it is not unusual for them to rest a cycle," a show representative explained.
"As we consider who will be matched up each season, there are a lot of factors that dictate which couples make the best pairings. We appreciate each of our dancers' dedication to the show, so this is a very difficult decision. Anna, Chelsie, Louis and Maks continue to be a part of the Dancing with the Stars family."
