It looks like 'X Factor USA' host, Khloe Kardashian, was excited about making her hosting debut on the show.

Really, really excited by the looks of things.

The 28-year-old's hosting skills really shone through on the first live shows of the US singing contest... and something else poked through.

Kardashian's wardrobe mishap

Her plunging neckline/sheer top/no bra combo brewed up the perfect storm for an untimely nip appearance.

Despite the on screen intruder, Kardashian and co-host Mario Lopez, carried on with their hosting completely unaware.

'X Factor' mogul, Simon Cowell, wasted no time in voicing his opinion.

I think the air conditioning is on high tonight looking at khloe

After the show, Kardashian took to Twitter after becoming aware of the incident.

Dear Khloe Kardashian, Put on a bra or at LEAST a pastie. Seeing way too much nip action right now.

...and some were supportive, just like the missing bra.
