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.
The show starts its third season in the fall.
