SAN DIEGO, Calif. -- Olivia Wilde has gone from rawhide to in the raw. The House star is currently shooting Cowboys and Aliens with Harrison Ford and Daniel Craig. And yes, in one scene, she's in danger of significant chapping.

So reports an enthusiastic Adam Beach, who plays Ford's henchmen in the sci-fi western.

"We just finished shooting Olivia Wilde naked in front of a bonfire in front of 500 Apache warriors," Beach says. "That was beautiful. You won't get to see what I saw, but you'll get a glimpse."

Asked about the nude scene, Wilde laughs. "Did Adam Beach talk to you? Adam Beach is the best. Last night, we did a scene where I'm naked in front of a group of couple hundred Apache. Pretty amazing, pretty interesting."

Not that she's only wild west cheesecake in the film, due out next July. "I do kick-ass in this. I love doing action movies ... This movie is so much fun for me."
