Khloé Kardashian is crossing over from reality T.V. star to reality T.V. host and the transition has her a little rattled.
"I've never hosted before," she said. "I mean, what if I get kicked off the show because I say something so bad? That is what I'm nervous about, but listen, I can't be anyone else but myself. I just have to control the language a little bit."
Of all the Kardashian sisters, little sister Khloé is known for acidic tongue and quick wit, which was in full form this afternoon.
"We really hate each other," she joked about co-host Mario Lopez. "I'm so sick to my stomach that I have to be by his side. You know when you're that unattractive it's just hard to be with someone."
A friend of the family, she added that Mario is "the nicest guy" and working with him will "take the pressure off."
"I think we're going to have fun; we've known each other for awhile," she said. "I feel I'll be comfortable around him, so he'll make it easy for me."
Earlier this week, Khloé gushed to Capital FM in the UK about how much she enjoys judge Britney Spears.
"I think [Spears is] so funny and amazing," she said. "I am actually surprised at how honest she is on the show. I thought she would be more quiet and reserved. I think she's hysterical."
The X Factor will go live on Nov. 1 on FOX.
