Last night saw reality TV beauty Khloe Kardashian make her hosting debut on the X Factor USA. However, not everyone was paying attention to what the star was saying the star suffered a wardrobe malfunction when her nipple became visible through her sheer shirt.
Opting for the smart look, Khloe wore a purple low V neck shirt with an A-line skirt. However we think Khloe should have thought about wearing something underneath the shirt as her nipple became exposed as she presented the show with co-host Mario Lopez.

Too focused on co-hosting the show, which saw the final 16 acts take to the stage to perform live for the first time, Khloe didn't realise her wardrobe malfunction until after. Making light of her wardrobe malfunction, the Keeping Up With The Kardashians beauty tweeted:
"I think I had a little nip action earlier. LOL."
Also finding the funny side to Khloe's nip slip, Simon Cowell, who was joined on the panel by Britney Spears, Demi Lovato and L.A. Reid, wrote on his Twitter page: "I think the air conditioning is on high tonight looking at khloe."
However, Khloe and Simon weren't the only ones to comment about her nipple as fans took to the social networking site to also share their comments. One wrote: "Just turned on the X Factor... why is Khloe Kardashian's nipple staring at me. I don't like it", whilst another wrote:
"Who can concentrate on the singing when Khloe's nipple keeps distracting me?!"
