Khloe Kardashian's firing from 'X Factor' is a ''blow''.

The reality TV star has reportedly been axed from the show after just one season and friends of Khloe, 28, believe she will be devastated when the news becomes official.

A source told HollywoodLife: ''You know Khloe's going to be shocked. It's just another blow for Khloe and her ego has to be knocked a bit.''

Khloe - who is married to basketball player Lamar Odom - previously revealed she was asked not to take any hosting lessons before she started, leaving her unprepared for what to expect.

She explained: ''I've never done live TV before, and I was asked to not do any hosting lessons because they wanted me to be just myself. I found the day before because the stage was just built, that I couldn't read the teleprompter without glasses, so I had to get contacts the day before.

''Just learning how there's a screaming audience and you don't yell because the mic is right there ... I will have an earpiece in my ear, and while I'm trying to read the teleprompter then I have someone counting down ... and they're like, 'Okay, ask Simon [Cowell] this or that' ... There were so just so many pieces I never knew were involved in live TV.

''I do feel like through every show I got better and better, but my first week I literally was like, 'I am going to die. I want to fake a heart attack.'''
