Los Angeles (CNN) -- Mario Lopez and Khloe Kardashian are in the final stage of negotiations to co-host the "The X Factor," a source close to the show told CNN Tuesday.
"Those two want to do it, and the show is keen to have them," the source, who asked not to be named, said.
Producers of the Fox TV music competition and managers for Lopez and Kardashian are putting final touches on the hosting deals, the source said.
The 2012 season's "live" shows, which require a host, begin on November 1.
"X Factor" started second season on U.S. television last month with audition episodes in which Britney Spears and Demi Lovato joined L.A. Reid and Simon Cowell on the judge's panel.
First season host Steve Jones left the show earlier this year, along with judges Paula Abdul and Nicole Scherzinger.
