Jul 01, 2015 06:26 PM EDT

Last season's Dancing with the Stars was quite a dazzling time for both the celebrities and dancers, and fans can't help but wonder who will be dancing next season.  This is what we know on Dancing with the Stars Season 21 Cast Rumors and Air Date.

According to Fashion Style, some of the rumored celebrities that will appear include singer Ricky Martin, Maureen McCormick (Marcia from The Brady Bunch), Chris Colfer (Kurt from Glee), model Christie Brinkley, actress Heather Locklear, and singer Nick Lachey, who's brother Drew Lachey won in Season 2.

Gossip Herald has even more predictions that include Amanda Bynes, Amber Rose, Steve Ballmer, Jalen Rose, Jamie Chung, Demi Moore, and even last season's winner, Rumer Willis, according to Vine Report

One rumor that has arisen on the Pure DWTS site is that Marilu Henner could be joining the cast.  On a recent interview on The Today Show, she was asked about Dancing with the Stars, and she said: "I don't know...we'll see?"  Marilu Henner has been in many films, but is often best known for her role on the TV show Taxi

One big name that has been dropped is Bruce 'Caitlyn' Jenner.  Considering that he has been in the spotlight a lot lately since the transgender announcement, it would be surprising if he appeared on this show.  However, there are already rumors on the Hollywood Reporter that both competitive dancers Derek Hough and Mark Ballas are vying to be his dance partner. 

Speaking of stars of the Keeping up with the Kardashians, there is a rumor that Rob Kardashian, who finished in second place during season 13 of DTWS, could be back for a "one night only" appareance, according to Radar Online

Another rumored star could be Britt Nilsson.  Yes, she did not win when competing on Season 19 of The Bachelor, but they kept her around for this year's The Bachelorette.  Of course, she was kind of eliminated again from that, so perhaps she could join up on DWTS in the Fall, joining the ranks of many The Bachelor alums like Melissa Rycroft, Chris Soules, and Sean Lowe. 

Then there are other names like Keke Palmer, who could easily win considering her music career and acting from True Jackson, VP.  Then there is a rumor of Stephanie Courtney.  In case you are not aware, Stephanie Courtney is better known as Flo, that Progressive Insurance agent from those many, many commercials.  Yeah, let's see how she fares on the dance floor.

Dancing with the Stars will return to ABC for its 21st season on September 14th at 8 PM EST, and then the Dancing with the Stars: The Results will return one week later on Tuesday, September 22nd.  Before the show premieres, there is always a segment on Good Morning America that officially announces the cast, and the best time for that release date is sometime in late August.
