Khloe Kardashian and Mario Lopez kicked off their co-hosting duties for the first time on The X Factor USA last night and Khloe made quite an impact. Kardashian was doing quite a good job as co-host but gave fans a treat when she had a bit of a nip slip.

Khloe did not even notice the wardrobe malfunction, until head judge Simon Cowell discreetly pointed it out to her. He said, “May I say, Khloe, you're looking very sexy tonight. I think the air conditioning's on high tonight. It's very distracting.”
However, everyone managed to see the funny side of the slip, including Khloe herself. After the show had finished, Kardashian took to her official Twitter account to tell her followers, “I think I had a little nip action earlier Lol (laugh out loud).”
