Dancing With the Stars Season 20 has just wrapped up and already, the rumor mill is already on full throttle for Season 21 after ABC network has officially renewed DWTS, confirmed When Will.

The names of those rumored to be appearing in Dancing With the Stars Season 21 are Bruce Jenner, Amanda Bynes, Amber Rose, Steve Ballmer, Jalen Rose, Jamie Chung and Demi Moore, mother of Season 20 co-champion and actress Rumer Willis (Rumer won the DWTS Season 20 tilt with Val Chmerkovskiy), according to She Knows Reality TV Magazine.

A report by The Hollywood Reporter, Bruce Jenner is in serious talks with ABC to compete in Season 21 of Dancing With The Stars. And since the former Olympian has completed his transition to becoming a woman, the producers of the show are now busy looking for a possible dancing partner.

The report said that Derek Hough and Mark Bellas are interested in becoming Jenner's partner should he join the competition when the long running show returns for a new season. It will be an interesting twist for Dancing With The Stars if Jenner will compete in the next season as it will be the first in the show's history to top-bill a same-sex dancing partner.

Also on the rumor mill, another "Keeping Up With The Kardashians" star is expected to join Dancing with the Stars Season 21. Jenner's son-in-law Rob Kardashian, is rumored to make a comeback in the competition after joining the show in season 13.

A source told RadarOnline that the youngest Kardashian has been given an open invitation to rejoin the show and the producers have offered to also ask Rumer Willis and Charlotte McKinney to spend time with him in the long-running dance reality franchise.

However, the 28-year-old Rob needs to lose some weight before he finally agrees to a return stint at Dancing With The Stars.

The source added, "Rob hasn't ruled it out," and described the young Kardashians as "the happiest anyone ever saw this kid was when he was dancing every day." Of course, the $50,000 cash offer for Rob to appear on again on Dancing With The Stars is truly enticing for any Kardashian.

Dancing with the Stars is an American dance competition show airing since 2005 on ABC in the United States, and CTV/CTV Two in Canada. The show is the American version of the British television series Strictly Come Dancing. Tom Bergeron is the Emmy-winning host, alongside Erin Andrews, who became co-host in season eighteen. The contestant pairs consist of a celebrity paired with a professional dancer. Past celebrity contestants have included professional and Olympic athletes, supermodels, actors, singers, and astronauts. Each couple performs predetermined dances and competes against the others for judges' points and audience votes. The couple receiving the lowest combined total of judges' points and audience votes is eliminated each week until only the champion dance pair remains.

ABC network has yet to announce when the Dancing With The Stars Season 21 will air.
