An official cast announcement won't come for a little while yet, but rumors are already surfacing which indicate just which celebrities are signing for the upcoming 25th season of "Dancing with the Stars."

Following reports that "Property Brothers" star Drew Scott and WWE wrestler/reality star Nikki Bella had signed on for the new season, People Magazine reports that husband and wife reality stars Nick and Vanessa Lachey have also signed on as celebrities competing for the Mirrorball trophy.

If the couple, who are parents to a son, Camden, 4, daughter, Brooklyn, 2, and a son, Phoenix, 8 months, are in fact joining the show, they would mark the second married couple to compete against one another on the show, Season 21 saw Alexa and Carlos Penavega compete against one another, dancing with Mark Ballas and Witney Carson respectively. Alexa placed sixth in their season, while Carlos made it to the semi-finals before being eliminated.

Lachey's brother, Drew, also competed on the show during its second season. He won the Mirrorball trophy with partner Cheryl Burke.

ABC has not confirmed any casting rumors as of yet, and won't before the official announcement is made. It is expected that the cast will be announced sometime after Labor Day, according to host Tom Bergeron's twitter account.

The pros for season 25 were announced on Aug. 24 during a broadcast of "Good Morning America." Nearly the entire slate of pros featured in Season 24 returned, including Witney Carson, Keo Motsepe, Gleb Savchenko, Maksim Chmerkovskiy, Artem Chigvintsev, Peta Murgatroyd, Sharna Burgess, Val Chmerkovskiy, Lindsay Arnold and reigning champ Emma Slater. Emma's fiancé, Sasha Farber, and Kym Johnson-Herjavec are sitting this season out.

However, the pros taking their place are exciting cast additions. Alan Bersten, a troupe member who filled in for Maks for four weeks of Season 24 while he was out due to a calf injury, is officially joining the cast as a pro for the first time in Season 25.

Ballas, who took seasons 23 and 24 off to focus on a stint on Broadway, will also be returning to the ball room for the new season. In a post announcement interview with People Now, Mark teased some information about his partner, and admitted that her being on the show was a major part of his also agreeing to sign on again.

"She's lovely, she's gifted, and she's natural, I would say," he said. "We've known each other for a while. I've wanted her to be on the show for a while, but our schedules never lined up. And then I found out she was doing it, and then I had something in October that cleared. That was a big... like 'Okay, if you'll do it then I'll do it.' It all kind of lined up."

While it's unclear if one of the rumored women to be joining the cast is Mark's mystery partner, there is a chance one of them could be. Though he has most often been paired up with actresses or Olympic athletes in prior seasons, he danced with UFC Champ Paige VanZant in Season 22, with whom he placed second, which could make Bella a potential good fit as well. He also served as Kim Kardashian, Kristin Cavallari, and Sadie Robertson's partner in their respective seasons on the show, though Kardashian and Cavallari were both eliminated early in their seasons. He did finish second with Robertson.

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