"Dancing with the Stars" is coming to Australia with the complete set of contestants already unveiled. While fans in the U.S. are still waiting for ABS to reveal the celebrities set to grace the ballroom stage this year, media outlets already have an idea of who may end up joining the new season. 

For starters, rumor mills are dragging the names of Demi Moore, singer Ricky Martin, actress Maureen McCormick from "The Brady Bunch," model Christie Brinkley, "Glee's" very own Chris Colfer, actress Heather Locklear, and singer Nick Lachey, whose brother Drew emerged as the victor in season 2. 

There are also speculations that the likes of Amanda Bynes, Amber Rose, Steve Ballmer, Jalen Rose, and Jamie Chung are being eyed to join season 21. Meanwhile, "Taxi" star Marilu Henner suggested in an interview with "The Today Show" that she may be a contestant. 

But according to various reports. "Dancing with the Stars" is hoping that Caitlyn Jenner would join the show. However, it looks like fans won't see the 65-year-old Olympic medalist groove on the dance floor anytime soon as a source told Hollywood Life that money and scheduling issues as well as "a few other bumps in the road" won't make it happen. 

In the event that Caitlyn does manage to join the show's 21st season and attempt to get this year's mirror ball trophy, Val Chmerkovskiy wants to be her pro dance partner. In an interview with In Touch Weekly, he said that he has what it takes to be "Cait's partner for sure." 

"I've proven I can win the show, and I would love to have an opportunity to win it with somebody that no one else believes can do it," he said. "As long as you have the right energy, I am in it to win it."  

Meanwhile, stars such as Keke Palmer and Stephanie Courtney are also being rumored to join the show. 

"Dancing with the Stars" season 21 premieres on Sept. 21.
