Aubrey O'Day, Arsenio Hall and Clay Aiken all started out on Sunday night's Celebrity Apprentice before Donald Trump, taking a line from last week's advisors and former Celebrity Apprentice victors John Rich and Marlee Matlin, called O'Day "transparent' and fired her, leaving Hall and Aiken to duke it out for this season's victory.

"There are no losers in this room," Trump told Aiken, Hall, and O'Day before giving O'Day the bad news. "Whoever said I'm transparent, f–k t hem," O'Day said on her way out.

Hall and Aiken left the boardroom in high spirits. "I'm getting your ass," Hall said, before Aiken said, "You might want to rephrase that."

Aiken is ready to take on Hall. "This time I ain't gonna lose," he said, referring obliquely to his 2003 American Idol loss to Ruben Studdard in 2003. "I will sleep when it's all over. Until then, game on!"
