Who says you can’t go back to where you started? It’s a theory that somgstress Jennifer Hudson doesn’t subscribe to because she’s set to return to the scene where she became an “American Idol”, this time as one of the long-running TV show’s judges. Idol is headed for it’s 13th season on the air and has been one of the nation’s longest running prime-time entertainment programs. Hudson, who won the competition herself and went on to win an Oscar and a Grammy award, will replace Nikki Minaj, who’s leaving the show as well as singer Mariah Carey and Ramdy Jackson.
