In her debut episode of “The X Factor,” Khloe Kardashian proved herself to be a host who was capable, talented…and more than a bit chilled.

“I think the air conditioning is on high tonight looking at khloe” tweeted Simon Cowell last night, acknowledging that his show’s new co-host was appeared a bit more at attention than necessary.

Wearing a form-fitting, merlot-colored blouse, the middle Kardashian sister seemed to be getting upstaged by her nipples. Many viewers took note of Khloe’s manifested mammillas, and if they didn’t, Simon drove the point home when he mentioned it aloud while telling Khloe that she looked “absolutely lovely.”

After the show, Khloe confessed to showing up to work a bit more alert than she needed to be, tweeting to a fan who didn’t understand Simon’s reference: “I think I had a little nip action earlier LOL ‘@WeLoveKhloeKO: i dont get the air conditioning joke…”

Of course, Khloe’s fans laughed it off and remained in total support. “I’ve never seen Simon smile so BIG!” said Twitter user “Katie Lee.” Agreeing with the sentiment, fan “lauren” said: “haha I saw this.. it was kinda at the beginning of the show! its cool, most everyone has a nipple or two!” Meanwhile, “MMM_MS_AQUAFINA” said she enjoyed Khloe’s bubbly bosom, tweeting: “I think u should do that permanently..very great @ hosting..”

Nip Slips or no, Khloe seemed to be having a great time alongside fellow newbie Mario Lopez (who, as best as we can tell, kept his nipples undercover – for once!). “Already half way into the show – and I must say I LOVE LOVE LOVE my new job!!!” she tweeted at one point. Afterwards, she rushed across the street to the Staples Center (how convenient is that?!?) to watch hubby Lamar Odom make his regular-season debut. “Thank you guys so much for tuning in to The X Factor tonight!!! Now I’m rushing to Staples for the Clipper game!!!!”

Khloe and Mario seem to be getting solid reviews, the Clippers won the basketball game, and her fans seem to think the nip slip just makes Khloe seem even more sweet and accessible than ever before, so all in all, it was a good night. What do you think about Khloe’s adventurous hosting debut?
