Former "Real Housewives of Atlanta" star Kim Zolciak is reportedly joining ABC's "Dancing With the Stars" for Season 21. The reality star and mom of six, who's been battling plastic surgery rumors lately, is said to be the latest celebrity lacing up dance shoes for a chance to win the coveted Mirror Ball trophy. 

According to E! News, Zolciak will be competing on the upcoming season of the dancing competition show, which kicks off on Monday, Aug. 20. ABC has not confirmed the news, and Zolciak has yet to comment on the casting rumor. If the speculation is true, the 37-year-old "Google Me" singer will be following in the footsteps of her "Real Housewives" co-stars NeNe Leakes and Lisa Vanderpump, who also competed on the show in past seasons.

As previously reported, this season of "Dancing With the Stars" includes Nick Carter, Vine star Hayes Grier, Bindi Irwin, Chaka Khan and horse jockey Victor Espinoza. It's also been rumored that Paula Deen will be cooking up some dance moves for Season 21, along with Big Time Rush singer Carlos Pena. The official "Dancing With the Stars" cast is expected to be revealed on "Good Morning America" on Sept. 2. 

In other "DWTS" news, fan-favorite pro dancer Derek Hough will return, as well as Season 20 winner Val Chmerkovskiy, Sharna Burgess, Allison Holker, Mark Ballas, Peta Murgatroyd, and Artem Chigvintsev. 

Julianne Hough, Bruno Tonioli, and Carrie Ann Inaba will be back as judges, but Len Goodman decided to sit this season out because of scheduling conflicts. For Season 21, co-executive producer Deena Katz previously told Glamour the show was thinking about bringing "Swtich Up" night back, where pro dancers swap partners with another celebrity for one episode. The show could also add "America's Choice" again, which allows fans to pick which dance style and song the couples perform to.
