"Dancing With the Stars" Season 21 premiere is just around the corner. And though the complete celebrity cast list for the upcoming season has not been officially announced, four names have already been confirmed and revealed and they are Nick Carter, Paula Deen, Bindi Irwin and Victor Espinoza.

In a recent cast reveal, Aussie teen Bindi Irwin was announced as the first "Dancing With the Stars" Season 21 contestant. As previously reported, Bindi is the 17-year-old daughter of the late "The Crocodile Hunter" Steve Irwin. Her participation was also announced "Good Morning America."

Also joining Irwin was jockey Victor Espinoza, whose "DWTS" participation was announced on SportsNation. According to E! News, Espinoza became popular when he and horse American Pharaoh won the Triple Crown in 2015.

Two more celebrity names have also been announced to show off their skills in "Dancing With the Stars" Season 21 dance floor. Us Weekly revealed that Backstreet Boys member Nick Carter and disgraced Food Network star Paula Deen are also joining the cast.

Carter revealed that he has finally decided to sign on for the upcoming "DWTS" season after four consecutive years of offers. Though he is the first BSB member to compete on the show, he wasn't the first member of the Carter family to join the show since little bro Aaron was part of the ninth season cast.

"I'm excited," Carter said. "My brother was on it; he did great; and he's a great little dancer and entertainer so I saw it through his eyes throughout that experience. And there's a lot of competitiveness in me and I think there's a little something inside of me that says, 'Okay, I'm going to go there and represent the Carter name and do even better than what he did!'"

Meanwhile, celebrity chef Paula Deen is reportedly joining "Dancing With the Stars" Season 21 after turning down the offer of the hit ABC dance showdown in 2010. The 68-year-old controversial Food Network star admitted that her reason in turning down the offer was because she was fat, New York Daily News noted.

"They did ask me and I said no," Deen said at the time. "Fat girls don't look good sweating."

In addition to the aforementioned celebrity names, R&B legend Chaka Khan will also be taking her first steps toward the Mirrorball trophy, another E! News report revealed. And apart from the celebs, nine professional dancers have been reported to compete in the upcoming season, which include Karina Smirnoff, returning champ Val Chmerkovskiy, Derek Hough, Mark Ballas, Artem Chigvintsev, Allison Holker, Witney Carson, Sharna Burgess and Peta Murgatroyd.
