The E! reality star and Extra host replace The X Factor's season one host Steve Jones, who was axed in a bloodbath that also found judges Paula Abdul and Nicole Scherzinger without jobs in late January. Following the firings, Simon Cowell repeatedly stated that he hoped to hire two judges for the forthcoming season, one female and one male.

Kardashian had long been rumored to fill the position. Her friendship with new X Factor judge Demi Lovato helped seal her deal, a source said.

Meanwhile, Lopez's name only recently entered the fray. Other potential hosts said to have been on the shortlist included Corbin Bleu, Kevin Jonas and Kevin McHale.

Kardashian and Lopez screen-tested separately. It's unclear whether they've been on camera together yet.

The X Factor returned with its season two premiere on Wednesday, Sept. 12, with new judges Britney Spears and Lovato joining Cowell and L.A. Reid on the panel. Kardashian and Lopez are expected to appear when the live shows begin later this fall.
