Extra, Extra… Mario Lopez will be having an X-ceptional fall…

The 38-year-old Mexican American actor has reportedly signed on the dotted line to co-host Fox’s The X Factor alongside Khloe Kardashian, according to The Hollywood Reporter.

A source close to the show says that Lopez has officially signed on, while Kardashian’s reps and the X Factor team have agreed on all points of her contract, and paperwork should be signed shortly.

The Extra host and E! reality TV star replace The X Factor’s season one host Steve Jones, who was cut  in a massive talent slash 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.

A representative for Fox had no comment.

The X Factor returned with its season two premiere on Wednesday, September 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.
