An entire new set of contestants will be seen in the upcoming 'Dancing with the Stars' 2015 in Australia. Meanwhile, U.S. fans of the reality dancing show are still waiting for ABC to disclose the names of the celebrities who will be gracing the ballroom stage in the upcoming soon; several media outlets have offered hints of who may be joining the new U.S season.

According to Christian Today, to begin with, there are rumors suggesting that celebrities like Demi Moore, singer Ricky Martin, actress Maureen McCormick, model Christie Brinkley, Chris Colfer, actress Heather Locklear, and singer Nick Lachey, whose brother Drew won the show's Season 2, will be the probable contestants in 'Dancing with the Stars' 2015 Season 21.

In addition, speculations are rife that celebrities like Amanda Bynes, Amber Rose, Steve Ballmer, Jalen Rose, and Jamie Chung are also being eyed to join the show's Season 21. In the meantime, in an interview with 'The Today Show,' 'Taxi' star Marilu Henner suggested that she may also be a contestant.

Meanwhile, various reports have suggested that 'Dancing with the Stars' producers are hoping to rope in Caitlyn Jenner for the show. Nevertheless, if Hollywood Life is to be believed, it is unlikely the 65-year-old Olympic medalist will be seen grooving on the dance floor anytime soon. A source told the website that money and scheduling issues in addition to "a few other bumps in the road" will not make it happen.

In case Caitlyn does join 'Dancing with the Stars' 2015 Season 21 and makes an attempt to win this year's Mirror Ball trophy, Val Chmerkovskiy, who helped Rumer Willis to win the Mirror Ball last season, wants to be her pro dance partner. Chmerkovskiy told In Touch Weekly that he has what it takes to be "Cait's partner for sure."

Chmerkovskiy said, "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," adding, "As long as you have the right energy, I am in it to win it."

Meanwhile, there are also rumors that stars like Keke Palmer and Stephanie Courtney may join the show.

'Dancing with the Stars' Season 21 premieres on Sept. 21.
