The list of rumored celebrity contestants for season 21 of "Dancing With the Stars" continues to grow longer as the premiere episode draws closer, and names include several famous individuals that seem unlikely to join the show. 

Recently, a source told Hollywood Life that the showrunners of the long-running dance reality competition want to get Donald Trump in their show.

"The producers know what a lightning rod that would be, so when his run for the president is finished, they would love for him to join a future season of the show," the source claimed. 

But ABC decided not to talk about the possibility of Trump's entry into the competition, saying: "We do not comment on casting rumors."

The multi-millionaire decided not to comment on the casting rumors either. He is currently busy campaigning for the GOP bid. 

Meanwhile, "Pretty Little Liars" star Shay Mitchell is also reportedly joining the dance reality contest in its upcoming season. The rumors began when the Canadian actress told fans that she would love to join the show in its upcoming season, and she would love to be paired with the current Mirror Ball trophy winner Valentin Chmerkovskiy. 

If Mitchell will join the dance competition, she will not be the first "PLL" actress to do so. In "DWTS" season 19, her co-star Janel Parrish got the chance to be paired with Chmerkovskiy and they managed to end up in the third. 

Another possible contestant for "Dancing With the Stars" season 21 is "The Bachelorette" season 11 Kaitlyn Bristowe. 

Caitlyn Jenner and NBA star Anthony Davis, two of the highly rumored celebrities for next season, already denied the rumors that they will join the dance competition. Jenner's rep told Entertainment Tonight that she has no intention of joining the show because of her hectic schedule in her new docu-series "I am Cait" on E! Davis, on the other hand, said in an article posted on Yahoo! that he does not want to embarrass himself. 

"Dancing With the Stars" season 21 premieres on Sept. 14 on ABC.
