Keeping up with the Kardashians just got easier.

Khloe Kardashian won't be back to host "The X Factor" in the fall.

A show source issued this statement: "Khloe Kardashian will not be returning to host 'The X Factor.' We really enjoyed working with her and wish her all the best in her future endeavors."

But Mario Lopez will return as "X Factor" host, Fox announced Monday.

Judges Simon Cowell and Demi Lovato are returning in the fall. Judges Britney Spears and L.A. Reid have left the show.

Cowell had nice things to say about Lopez in a statement: "I’m thrilled Mario is back for Season Three of 'The X Factor.' Hosting a live show and keeping the judges -- especially Demi -- in line, is not an easy job, but Mario is a pro and we are glad he’s coming back.” 

Lopez, host of "Extra," joined the Fox singing contest last season with Kardashian. In a statement, he said: "I’m looking forward to returning to 'The X Factor' team. We’re coming back stronger and better than ever, and I'm excited to check out all the new talent.”
