Season 25 is set to be a milestone one for ABC's "Dancing with the Stars," and in honor of the celebratory landmark, the season will likely pull out some unexpected surprises—starting with the pro dancers who are taking to the floor.

During a live broadcast of "Good Morning America," the pro dancers who will comprise one half of the couples taking to the dance floor for Season 25 were announced, and featured some faces that have been familiar to fans over the years, but who haven't been as frequently featured in the most recent seasons.

The full list of returning pros is featured below:

  • Mark Ballas: Mirrorball Champ, Seasons 6 and 8. Mark returns after taking two seasons off to star on Broadway and marry BC Jean.
  • Emma Slater: Reigning Mirrorball Champ
  • Lindsay Arnold
  • Keo Motsepe
  • Val Chmerkovskiy: Mirrorball Champ, Seasons 20 and 23
  • Peta Murgatroyd: Mirrorball Champ, Seasons 14 and 22
  • Artem Chigvintsev
  • Maks Chmerkovskiy: Mirrorball Champ, Season 18. Maks is returning after being forced to miss out on most of Season 24 due to an injury.
  • Gleb Savchenko
  • Sharna Burgess
  • Witney Carson: Mirrorball Champ, Season 19
  • Alan Bersten: Bersten is a first time pro who filled in for Maks during Season 24

The announcement that Ballas was once again returning to the stage for a chance at the mirrorball trophy was a nice surprise for fans of the show, though host Tom Bergeron had previously teased that some original pros were coming back to ABC 7 Entertainment reporter George Pennacchio.

"Hey #DWTS fans: @Tom_Bergeron just confirmed to me that two former pros will return for the show's 25th season," Pennacchio tweeted on Aug. 18.

Making his debut as a pro this season is Bersten, who both fans the Chmerkovskiy brothers campaigned to see promoted after he filled in for Maks after an injury sidelined him in Season 24. While he worked with Maks' partner, "Glee" star Heather Morris, she scored well on dances, eventually earning her first perfect score after Maks returned during Week 6 of the competition. However, the couple was eliminated later that night.

In an interview with IBT, Maks previously admitted he didn't know if he or Peta would be returning for the new season, admitting that they both wanted to prioritize their seven-month-old son, Shai, and had to consider what was best for them as a family before they committed to the show again.

"We obviously prioritize Shai, and it's important to both of us to make sure that our time with him is not being cut into. It's one of my main things that I want to be around all the time, and I see all the things that happen," he said.

Now that fans know which pros will be making an attempt to cha-cha, rumba and paso their way to the mirrorball trophy, the question remains as to which celebrities will be making an attempt to show off their potential dance skills. Fans will need to wait a little while longer for that official reveal, with Bergeron confirming on Twitter Aug. 16 that the reveal would be after Labor Day on Sept. 4.

However, while the official reveal won't be until then, two names have already been reportedly confirmed among the Season 25 cast. Entertainment Tonight has confirmed that Drew Scott from HGTV's "Property Brothers" will be competing on the new season, as will WWE Wrestler/Reality Star/John Cena fiancée Nikki Bella. ABC has not commented on the rumors about the two joining the cast.

"Dancing With The Stars" Season 25 premieres Monday, Sept. 18 at 8 p.m. EDT on ABC.
