London, Dec 31 : American actress Eva Mendes spoke out about her role in her new movie `The Spirit' where her bum was shown for real instead of just as a silhouette.

Mendes, 34, revealed that she enjoyed working with Scarlett Johansson again.

However, where her naked bum was concerned, she had no idea at all about it being shown.

"It was supposed to just be a silhouette of my naked bum! When I saw the film I was like: `Am I mistaken? Isn't a silhouette the outline of something?'" the London Paper quoted her as saying.

"I turned to Frank [Miller, the film's director] in nervous laughter and said: `That's not a silhouette, is it?' And he said: `No, but it's great!'" she stated.

The Spirit will be out on January 1. (ANI)
