"Khloe Kardashian has joked about her wardrobe malfunction on the first X Factor USA live show. Kardashian made her hosting debut on the talent competition last night (October 31) alongside fellow new presenter Mario Lopez.  However, her sheer top quickly became a topic of conversation on social networks and judge Simon Cowell made a comment during the broadcast, suggesting that her nipples were on show. Cowell also took to Twitter to joke about the incident, saying: &amp;quot;I think the air conditioning is on high tonight looking at khloe.&amp;quot; Kardashian has since laughed off the remarks, telling a fan: &amp;quot;I think I had a little nip action earlier LOL.&amp;quot; She later told another follower: &amp;quot;How crazy that I had no idea until those lights turned on! Ha! Of course it happens to me.&amp;quot; Photo gallery - The X Factor USA&amp;#039;s first live show:  Kardashian did say that she was enjoying her new gig, posting halfway through the broadcast: &amp;quot;I must say I LOVE LOVE LOVE my new job!!!&amp;quot; She also thanked her followers for &amp;quot;giving [her] courage to do this&amp;quot; and praised Lopez, saying: &amp;quot;You made me feel at home!
