Kardashian and the America's Best Dance Crew host are finalizing deals to join The X Factor's currently-airing second season and a formal announcement will be made this week, TMZ reported.
"Those two want to do it, and the show is keen to have them," a source told CNN on Tuesday.
Fox has been airing second-season audition episodes of The X Factor, which premiered September 12, thus far and has only featured Simon Cowell, L.A. Reid, Britney Spears, and Demi Lovato critiquing artists from the judging panel. However, the show will reportedly transition into the host-required live performance shows starting November 1.
Reports that Kardashian, the Keeping Up with the Kardashians and Khloe & Lamar star, had emerged as the frontrunner to serve as the new female co-host of The X Factor began surfacing last month and been followed by similar reports about Lopez.
