Olivia Wilde strips down to next-to-nothing in her latest, braless photo shoot.

The actress, who is currently promoting the highly-anticipated CGI film “Tron: Legacy,” posed for a sultry Details spread in nothing but a sheer beige shirt and American Apparel underwear.

The “House” actress is no stranger to racy outfits, however, as she sports a skintight rubber suit in “Tron,” in which she plays the cyber guide, Quorra, opposite Jeff Bridges.

In her interview with Details, Wilde says she didn’t have to add sex appeal to the cybervixen’s character.

“It was so beautiful that I didn’t need to play the character sexy,” she says of the black and glowing neon suit.

However, the 26-year-old New York City native admits that when she first saw the skin-tight gettup, she had reservations.

“I saw the boobs on the suit and I said, ‘Oh, hell no. I’m doing kicks and backflips in this thing?’” she says.

She explains that her character, Quorra, is reminiscent of Joan of Arc, “but with the hair of Karen O from the Yeah Yeah Yeahs. But still a total badass.”

Fans can see Wilde in all her rubber-clad glory in “Tron: Legacy” on Dec. 17.
