Hosting the 'X Factor' is the most nerve wracking thing Khloe Kardashian has ever done.

The 'Keeping Up With The Kardashians' star landed the job of co-host on the US show alongside Mario Lopez and while she is loving the experience, she admitted the first live show on Tuesday (30.10.12) was overwhelming.

She wrote on her website khloekardashian.celebuzz.com: ''WOW! What a week it has been! I just wanted to take a moment to thank ALL of you for the outpouring of support I received during this new and exciting chapter in my life. Hosting The X Factor is one of the most challenging, nerve wracking and THRILLING things I have ever done.''

Khloe acknowledged that it will take some time to perfect her presenting skills but is confident she will get better with each performance.

She added: ''Each night has a different format, and now that I have experienced both I am confident that I will only get better over time, but I couldn't have done ANY of this without the support, positive shoves and love from all of you. Thank you from the bottom of my heart for giving me the courage to do this. I love you madly!!!! (sic)''
