Khloe Kardashian’s X-Factor hosting days are over. The reality TV star has been told not to return for the next season – the show’s third – but her former co-host, Mario Lopez, will be.

According to TMZ, the network didn't give a reason for Kardashian's departure, but said, "We really enjoyed working with her and wish her all the best in her future endeavors." A source told old E! News that there is no bad feeling surrounding her exit, adding, "Everyone on the show had a great relationship with her and thought she was fun to work with." Lopez said in a statement: “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." And on the subject of Lopez's return, Simon Cowell said, "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 will join the returning judges Simon Cowell and Demi Lovato as the show’s core team. At least one more judge (presumably two) is yet to be announced. Producers previously confirmed former judges Britney Spears and L.A. Reid would not come back for another season.
