The X Factor is taking a new approach for Season 3 with a female-centric judging panel, RadarOnline.com can reveal.
"The producers and FOX have decided on their dream panel and they're in the very final stages of negotiations as the auditions start in just a few weeks," a source said.
It's understood 32-year-old Rowland -- who previously worked for Cowell on the UK version of The X Factor in 2011 -- and Rubio, 41, are considered the frontrunners.
The pair would replace Britney Spears and L.A. Reid, who both quit after season two.
Said one production source: "A female centric panel is something new to the show, but both the producers and Simon really think it's the right way to go."
According to the insider, Rowland and Rubio bring diversity to the show that had been lacking in previous seasons.
"Paulina is one of the most influential Latin celebrities in the world and Kelly brings some star power and experience since she judged on the UK version of X Factor a couple years ago," the source told Radar.
"All the women really get along well and Demi continues to have great chemistry and banter with Simon," the source added.
