Interesting view: Khloe Kardashian exposed her nipple in a sheer blouse live on television as she hosted the X Factor USA for the very first time on Wednesday
The Keeping Up With The Kardashians personality had opted for a plunging black long-sleeve sheer top with sequined detailing, which she opted to wear with no bra underneath.
She paired the ensemble with a tight-fitting black pencil skirt cinched in at the waist with a leather belt.
Standing alongside co-host Mario Lopez, Khloe was smiling as she underwent her hosting duties, seemingly unaware of the wardrobe malfunction.
Keeping a straight face: Mario Lopez did not seem to have any idea about Khloe's attention grabbing moment
AFterwards she joked about the incident on her Twitter account, saying: 'I think I had a little nip action earlier. LOL.'
But Judge Simon Cowell certainly took note, immediately taking to his own account to make a crude joke about the incident.
'I think the air conditioning is on high tonight looking at khloe,' he wrote on the social networking site.
The exposure also caused an social-networking sensation, with several users tweeting up a storm about the incident.
Keeping her fans abreast of the action: The reality television personality saw the funny side
'Just turned on the X Factor… why is Khloe Kardashian's nipple staring at me. I don't like it,' one user wrote.
'Who can concentrate on the singing when Khloe's nipple keeps distracting me!' another one Tweeted.
But Khloe's hosting skills did not receive as much positive publicity as her nipple.
The Washington Post wrote: 'Odom came across like the novice she is, shouting her lines despite the mic clutched in her hand and making awkward small talk with contestants and judge and executive producer Simon Cowell.'
And it added: 'Odom sounded like an oddly flirtatious schoolgirl as she introduced Cowell as “Mr. Sexy.”'
It is unknown whether Khloe was aware that her blouse was so sheer that her modesty would be exposed.

But Simon will no doubt be delighted at all the extra publicity his struggling show is getting off the back of the incident.
And it is not the first time she has bared her nipple on live television either.
For in June last year Khloe highlighted the perils of fashion on the Live with Regis & Kelly show when she accidentally exposed her breast for six minutes, live on the daytime TV program.
