Fifty Shades of Grey star Dakota Johnson seemed to have revealed a lot of skin during the film's raciest sex scenes. It turns out that Dakota's pubic hair was added into the scenes post production. 

Film cinematographer Seamus McGarvey, has recently revealed that Dakota's pubic hair was edited into the scene and she even had a bum double for the naughty spanking scenes.

"She had kind of a patch that went over her pubic area, and right round her whole body." Seamus said.

Her co-star Jamie Dornan, who plays the notorious Christian Grey, donned a 'penis pouch'. Johnson, who played Anastasia Steele, was given similar "modesty-protecting underwear".

This means that those naughty bits exposed during the film's raciest scenes were a result of tricks done in the editing room.

"We were in the curious situation, in post-production, of adding pubic hair," he said. "I wouldn't say it was one of the highlights of my career, but it certainly was one of the most surreal scenarios."

McGarvey also revealed that a butt double was cast for Dakota for the hot spanking scene where Christian Grey spanks her bum with a belt

Dakota Johnson had also opened up about her 'heinous sex sex scenes' with Dornan and has revealed that being Anastasia Steele was also a surreal experience for her. "Even now there are moments when I think, 'What the f*** have I done?" the actress said.

Dakota has also revealed that she has no problem when it comes to exposing her body and sex scenes. 

"It's true that I'm not ashamed of my body. I'm comfortable and I think more women should be more confident. I think nudity and sexual scenes in movies are beautiful when they're tastefully done," she said.
