Kristen Stewart opened up to talk show host Craig Ferguson about her latest film, “On the Road” Monday night while on the "Late Late Show."

“'That was like the most terrifying experience of my life. It was fun in the end, though,” she said about her naughty dancing scenes.

Stewart, who accepted the role when she was 17-years-old, has nude scenes in "On the Road," but apparently the "Twilight" star did not even get nervous preparing for those scenes. 

“It didn't bother me,” Stewart told MTV News at the Toronto International Film Festival in September.

In one scene, Stewart is on a bed with her body exposed, as she plays the character Marylou, who is a 16-year-old bride. She is also in a topless scene while riding in a car with two co-stars and simulating sexual acts. 

“You can do no wrong with [director Walter Salles]. He puts so much inside of you. In the four-week rehearsal process, it was okay to ask any question, to bring up any story, to really over-analyze everything and intellectualize everything.

Once we got on set, it was so about just breathing and letting it happen. He put so much trust in us, so it was like, "Okay, so I have to take my clothes off?" It's so not a big [deal],” Stewart added.

The film is set in the 1940s and the cast of "On the Road" also includes Amy Adams, Viggo Mortensen, Kirsten Dunst, Steve Buscemi, Terrence Howard and Elisabeth Moss. The movie is scheduled for release on Dec. 22.
