New X-Factor host Khloe Kardashian phoned into Ryan Seacrest's radio show to talk about her recent X-Factor gig, and has admitted to being daunted by the task, E! reports.

First, though, she had to dispel the myth that she knew about her new role all along. "I'm not a liar. I like to say what it is. Everyone thought that I was just BS-ing everyone," she explains. "They were like, 'So you got the job?' I was like, 'I promise you, no one has confirmed anything with me. I would tell everyone if I did!' I was just waiting for someone to tell me, but everyone knew before me!" Even though she won't be alone in hosting the popular talent show, with Mario Lopez set to halve the duties with her, Khloe is still scared of what she has to do. "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," she joked.

But in all seriousness, she's glad of the co-host. "I mean, he's seriously the nicest guy ever. I'm in good company," she says. "He's great at what he does, so it takes some of the pressure off of me because I am nervous. I've never hosted before. I think we're going to have fun; we've known each other for a while. I feel I'll be comfortable around him, so he'll make it easy for me."
