If there's one thing that Simon Cowell loves, it's his famous white shirts.

The X Factor judge is often spotted wearing a white shirt during the competition show as well as red carpet events. While Cowell loves his style, his X Factor co-star Demi Lovato doesn't feel the same way. In fact, she said Cowell's choice in clothing has a negative affect on the show.

Kelly Rowland Has A Crush On Simon Cowell

"We're trying to reach to a younger demographic and I just don't feel like we are going to accomplish that when he's showing more cleavage than Britney and I are," Lovato joked on the Conan O'Brien show in 2012 about Cowell's attire.

Cowell also wears a white shirt in a new promo photo for season 3 of The X Factor. Coming this fall, the show includes two news judges - Kelly Rowland and Paulina Rubio and the first trailer for the new season was released in July.

While the only male judge deems Rowland a "total professional" in the clip, the former Destiny's Child singer is heard telling a male contestant, "how you doing there cowboy?"

Simon Cowell's New Attitude For New Season Of X Factor

Addressing the other female judge, Cowell said, "I think everyone is going to understand Paulina." However, what comes out of Rubio's mouth following his remark is quite difficult to comprehend.

The small rivalry between returning judge Demi Lovato and Cowell is also apparent. The Heart Attack singer teases the 53-year-old about his age but still, Cowell admitted that the 20-year-old has a more respectful attitude this year.
