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.
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.
After the show, Kardashian took to Twitter after becoming aware of the incident.
The audience at home was divided, some were shocked...
...and some were supportive, just like the missing bra.
