Rebel Wilson has opened up about why she refuses to get naked on film.

In the July issue of Marie Claire, the Aussie star said she was asked to get her kit off in the Sacha Baron Cohen flick Grimsby, but chose to use a body double.

“They wanted full-frontal nudity,” she said. “We write in the contract, specifically, ‘No nudity’. They got in another girl — this larger burlesque dancer from South Africa — to be a nude double. And they got her to do all this stuff. Sacha [Baron Cohen, who wrote and starred in the movie] would go, ‘See, she looks good’. I’m like, ‘I’m not doing it. I don’t care what you say’.”

While she would consider getting nude for the right role, Rebel said comedy’s treat it less sensitively.

“You want to know that the people [behind the camera] have a certain sensibility and decency,” she said.
