Khloe Kardashian suffered a wardrobe malfunction on her first day hosting "The X Factor (US)" and she has talked about it. On Thursday, November 1 after the second live show, she told reporters, "I kind of looked. From my angle I thought maybe it was nipple-y, but from what I heard, it was entire areolas. That was what the production told me in my ear. They were like, 'Your areolas are out.' "

Speaking of her outfit choice, the reality TV star revealed, "[The blouse] came in the mail and I wanted to wear it. It's lined with nude lining, it's not just like a sheer top. I had no idea, with my dressing room lights you didn't see a thing. We were rushed and went on stage."

Then, she saw Simon Cowell "sort of doing something like this [points to her chest], and I thought he meant my hair. Then I hear in my ear, 'We've got to fix your shirt.' I didn't know what they were talking about and I heard, 'Full areola is out.' "

Sharing how her husband Lamar Odom reacted to the wardrobe malfunction, she said, "We talked about the show, but I just forgot that part. Today [after watching the show] he texts me, 'Um� make sure you're not showing your nipples tonight.' "

Simon himself wasn't really bothered by the nip-slip. "No, I thought it was hilarious," he commented. "Your first live show, you don't wear a bra, and the studio's freezing, of course."

Making her debut on the FOX reality show on Wednesday, Khloe wore a purple blouse with plunging V-neck. Noticing that the co-host's nipple was a bit exposed, Simon enthused, "You're looking very sexy tonight. I think the air conditioning's on high tonight. It's very distracting."
