Clay Aiken has made it all the way to the Celebrity Apprentice finale and will have to compete against Arsenio Hall in hosting a charity event. Although eliminated contestants were brought back to help the men set up the events, Clay finds it counterproductive to have Aubrey O'Day on his team and gets frustrated at her presence.

VIDEO: Aubrey O'Day Turns 'The Apprentice' Into 'The Aubrey Show'

When Aubrey tries to steal the show and take over Clay's project, he overrides her duties, which doesn't thrill Aubrey. "Clay asked me to do this entire job and if you ask somebody to do it you have to trust that they'll do it, but he's trying to step on everyone's toes so he feels like he's the man in charge" she says in a later interview. "In his words, we all need to remember that it's 'Clay's show,' but if I wasn't here he wouldn't have a show."

Clay explains that he is merely looking out for himself and making sure that everything suits his liking. "I've got to have my hand in everything because it is my project," he says. "Plus, I'm playing for money for the National Inclusion Project. This is a charity that I set up nine years ago, so winning is extremely important to me because it's not just any charity, it is my charity."

The drama carries over to the event, as Clay becomes annoyed with Aubrey when she steals the spotlight when Mr. Trump arrives at the party. "Aubrey jumps in and starts walking forward with Mr. Trump as if though I'm not there," he gripes. "Aubrey likes to take things over. She's very passionate about the stuff that she does, but I'm going to my very best to show Mr. Trump that I'm in charge."

Find out if Clay can manage to win The Celebrity Apprentice despite his rivalry with Aubrey this Sunday at 9 p.m. on NBC.
