Does Simon Cowell have rocks in his head? Yes, but the sparkly kind. The 'X Factor' judge and creator reportedly is eyeing Rihanna for his panel ... as well as another pop star that will raise even more eyebrows: Chris Brown.

The Sun reports that Cowell loves RiRi's vivacious personality in addition to being a fan of her music, and he thinks she can save the struggling ratings on the Fox series, be it here or across the pond. With L.A. Reid and possibly Britney Spears leaving after this season, he may need a big name to prop the show up.

“Simon is a huge admirer of Rihanna and knows she’s star quality," a source told the tab. "As well as bringing an aura to the panel thanks to her current standing in music, she is also feisty and will make great TV. Simon loves these sort of characters.”

But it doesn't stop there. A source added that Cowell is also considering Brown for a part on the panel. (Considering his recent excursions with ex Karrueche Tran, that may not end well for anyone involved.) “The U.S. 'X Factor' has improved on the first season’s ratings but it’s got some way to go to reach Simon’s expectations," the source dished. "Adding Chris to the panel will certainly create a talking point.”

While Breezy may prove more trouble than he's worth (can you imagine the protests and petitions this will garner?), Rihanna has a rapport with Cowell. The 'We Found Love' singer joined him for the judges' houses episodes on the stateside series. Still, her grueling schedule may prove a tough one to deal with in terms of production -- and her U.K. series 'Styled to Rock' was a ratings flop.
