Olivia Wilde is arguably one of the hottest actresses today -- but even she gets self-conscious when filming nude scenes. While stopping by the 'Late Show With David Letterman' to promote her new film, 'Third Person,' Wilde talked what it was like to be naked in front of the camera.

"Not only did I have to [film this one particular nude 'Third Person' scene] again and again, but this was a scene in which I was running down stairs naked -- which no one should ever do on camera," the star emphasized, laughing. "It's awkward. … There's things that no one should see. The body does things that it's not supposed to."

"And people are looking at your stuff," Letterman chimed in.

"Yeah! And it's jiggling," Wilde admitted, doing some hilarious hand motions. "It's moving."

Still -- her 'Third Person' nude scenes are something to look back on fondly.

"It's great now that I've had a baby," she revealed. "I can look at it and be like, 'Yep -- that's how it once was.'"
