Last week's fiery episode of Celebrity Apprentice saw contestants Aubrey O'Day and Arsenio Hall lashing out at each other. However, this bitter feud has apparently gone beyond what viewers  actually saw on Sunday night.

In a new interview with Us Weekly, O'Day revealed more about Hall taking a shot at her after she took credit for her team's win. Although the pop-singer was visibly upset after the rant, O'Day  apparently is delighted for being the reason for his resentment toward her.

I guess it's flattering that I upset him so much, the 28-year-old was quoted saying to the publication. Arsenio gets worse in the next episode, when he calls me a whore. He doesn't want strong women to have too much of a voice. Typical in this industry.

It all started when Donald Trump gave contestants the task of producing an interactive health segment to promote Walgreen's program, according to Reality TV World. Hall, who assumed his role as project manager, was enraged with O'Day for taking complete control of the team in executing the challenge.

The Us Weekly said that O'Day, who was also a former late night host, stormed out of the boardroom after Hall repeatedly complained about her being selfish and controlling. O'Day pushed aside reports of her walking off the show and said that she was just warming up.

According to the publication, the episode also featured Hall referring to O'Day as a stank a-- and told the other contestants, I Googled her and a naked picture with a gut popped up...f--- her!
