With less than a month to go before the Dancing With The Stars fall 2016 cast hits the ballroom to perform for the very first time, more lineup information surfaced on Aug. 25 from a variety of sources. Which former pro champions will return to the hit reality show? Which other Mirrorball Trophy winner announced that he's sitting out DWTS season 23 after 21 straight appearances? Read on for the casting details.

Maks Chmerkovskiy returns to the DWTS pro cast

A day after Maksim Chmerkovskiy was spotted taking a selfie with alleged DWTS season 23 celebrity cast member Amber Rose, the 36-year old Ukrainian heartthrob confirmed that he will return to the pro lineup via Good Morning America.

Chmerkovskiy, who last appeared as a prowhen he won season 18 with Olympic gold medalist Meryl Davis, said hewanted to continue the "feeling of positivity" he got from appearing alongside younger brother --and fellow Dancing with the Stars 2016 cast member-- Valentin Chmerkovskiy during their successful summer tour. Other dancers returning to compete for the Mirrorball Trophy after absences include Allison Holker, who gave birth to her second child earlier this year, and Gleb Savchenko, who last appear on the US version of the show during season 10.

Also returning to the ballroom after a single-season absence is two-time DWTS winner Julianne Hough. PureDWTS spilled the news of Hough's return to the judges' table, and DWTSGossip added that "It appears ABC/Disney pushed for #JulianneHough's return as a #dwtsjudge"

Dovolani ends 21-season DWTS streak

Of course, when dancers are added to the cast list, others are removed, and following Maksim Chmerkovskiy's announcement, Tony Dovolani revealed via Instagram that he will not compete during season 23.

The 43-year old native of Kosovo began his 21-seasonDancing with the Stars career during season two, when he partnered Stacy Keibler to a third place finish. He went on to work with a variety of interesting celebrity characters, including Kate Gosselin (season 10), Leah Remini (season 17), and Melissa Rycroft, with whom he won the all-star season. Dovolani wrote that he planned to spend his time away from the show visiting with DWTS fans around the country, tending to his dance studios, working to grow the Tony Dovolani Foundation, and spending time with his family.

He wished the Dancing with the Stars cast, whom he called his "second family," the best during season 23.

The Dancing with the Stars fall 2016 season premieres Sept. 12 on ABC. Although alleged celebrity contestants include Amber Rose, Disney star Jake T. Austin, soap actress Emma Samms, embattled Olympic swimmer Ryan Lochte, and Little Women: LA star Terra Jole, the full DWTS season 23cast will be formally revealed on Aug. 30 during GMA.
