Clint Black heard those dreaded two words from Donald Trump on Sunday: 'You're fired.' The country star was booted from 'The Celebrity Apprentice' after losing a challenge for which he was thought to be the frontrunner -- writing a commercial jingle. But Black's song for Chicken of the Sea canned tuna was not chosen, and, being that he was the project manager for the challenge, he was fired.

Black wasn't the only contestant let go on Sunday. Jesse James and Brande Roderick were also let go after an impromptu round of interviews with last year's 'Apprentice' champ, Piers Morgan.

Black joined the 'Apprentice' cast to help raise money for the International Rett Syndrome Foundation. He raised $20,000 on Sunday's show for the charity.
