The not-so-secret 'Celebrity Apprentice' cast has finally been officially revealed, with John Rich as this season's country music representation. The names were announced last night by the show's boss and host, Donald Trump, on NBC's 'Late Night With Jimmy Fallon.'

It comes as no surprise that John is appearing on the show. The member of the award-winning duo Big and Rich made several hints in recent months about being a contestant, and was also spotted in New York City by several AOL staff members, selling pizza for one of the show's episodes, as seen in the photo above.

For the fourth season of the reality competition show, John joins an eclectic mix of celebrities who compete against each other to raise money for the charity of their choice. Other stars on the show include LaToya Jackson, Gary Bussey, Star Jones, NeNe Leakes, Jose Canseco, Lisa Rinna, David Cassidy, Niki Taylor, Richard Hatch, Marlee Matlin, Meatloaf, Mark McGrath, Playmate model Hope Dworaczyk, Lil Jon and Dionne Warwick.

Getting a diverse list of stars to appear on the hit NBC show is getting easier, thanks to the success rate of the winners. "When we did the very first Celebrity Apprentice people didn't know whether to do it," Trump tells People. "But then everyone has seen all the winners have gone on to all these great things. Piers Morgan with CNN. Joan Rivers's career took off again. I can't turn on the TV without seeing Bret Michaels. He is the big superstar. They've all done so well."

The business mogul clearly can't divulge the winner, but he does have high praise for his latest country contestant, who raised money for St. Jude Children's Hospital. "John is very clever," Donald states. "He's very smart."

Previous country artists who appeared on 'Celebrity Apprentice' include Clint Black and Trace Adkins, who placed second in 2008.

'Celebrity Apprentice' will premiere on March 6 at 9:00 PM ET.
