In what was a very shirt stint as the co-host on Fox's 'X Factor', Khloe Kardashian will not be back for the next season. 

If you think there is a revolving door at the 'X Factor , you might be right. As soon as someone is brought in, it seems they are gone. Simon Cowell is the only person left from the first season. Now, Khloe Kardashian is out.

Fox announced yesterday that she wouldn't be back, but sources say that it's because she wasn't asked back. Theory is that Cowell brought in Khloe to increase ratings, and it didn't happen. LA Reid has also elected not to come back for the third season, as well as Britney Spears. Demi Lovato however will be back as a judge.
