Khloé Kardashian revealed more than just her hosting talents last night on her X Factor debut!

Wearing a flowy purple top and curve-hugging pencil skirt with heels, the youngest Kardashian stepped on stage with co-host Mario Lopez for this season's first live show, but it’s safe to say all eyes were on her— more specifically, on her chest.

Though Khloé’s top wasn’t exactly sheer, the busty brunette didn’t leave much to the imagination, as she appeared to be going braless under her blouse.

At one point, blunt judge Simon Cowell even pointed out the fact that Khloé was...well, pointing out.

"May I say Khloé, you're looking very sexy tonight,” he flirted with the host before adding, “I think the air conditioning is on high."

Khloé laughed and quickly quipped back, "You love it!”

Simon’s response? "It's very distracting." And we all know it takes a lot to throw Mr. Cowell off-course, but apparently a visible nipple does the trick!

We look forward to seeing more of Khloé (no pun intended) on tonight’s show, where 12 of the 16 acts will make it through to next week. Be sure to tune in tonight at 8 p.m. on FOX.
