Olivia Wilde prepared for her role as an exotic dancer in a new movie by spending time with real life strippers.

The Tron: Legacy star sheds her clothes to play a stripper in Butter and she learned the tricks of the trade from girls working at a club in Louisiana.

She tells New York Post gossip column Page Six, "We went down to Action Central Cabaret in Shreveport, Louisiana, and I got to hang out in the locker room with the strippers, and they were so sweet. They were really helpful. But also being able to hang out with the strippers let me know a little about the logistics of working at a strip club.

"It’s really an under-appreciated dance form.”

The actress also read Diablo Cody’s book Candy Girl, which tells the story of the screenwriter's brief stint as a stripper.

She adds, "That was the most useful thing."
