NBC has gathered a very interesting mix of candidates for the second season of The Celebrity Apprentice, and judging from the new preview it looks like there are plenty of clashing personalities to fuel the new two-hour episode format. Last year's winner Piers Morgan makes a cameo and there's a clip of him saying, "This makes me and Omarosa look like a tea party!" I wonder which celebrities become embattled competitors on the show; maybe Joan Rivers and Dennis Rodman? Any guesses? Check out the preview below.
