X Factor: Khloé Kardashian Out, Mario Lopez Stays On

Monday April 22, 2013 05:00 PM EDT

Khloé Kardashian is left out following the latest game of musical chairs on The X Factor.

Fox said Monday that while Mario Lopez is returning this fall as host of Simon Cowell's music competition series, Kardashian will not be joining him.

Cowell's series, which has never quite met ratings expectations, is in the midst of turnover with its judging panel, too.

Cowell and Demi Lovato will be returning, but Britney Spears and record producer Antonio "L.A." Reid left and have not been replaced yet.

The show starts its third season in the fall.
