The Extra co-host Mario Lopez is coming back for another season hosting Fox’s The X Factor, but Khloe Kardashian is not. “Khloe Kardashian will not be returning to co-host The X Factor. We really enjoyed working with her and wish her all the best in her future endeavors,” X Factor producers said today. Both Lopez and the E! reality star were named as the new hosts of the competition series’ second season in October 2012. A seasoned hosting pro, Lopez easily fronted the show but Kardashian struggled, earning the mockery of many viewers. In today’s announcement about Lopez’s return, X Factor’s main man made no mention of Kardashian’s departure. “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,” Simon Cowell said in statement.
