If you thought Jamie Dornan's body was too hot to handle in the megahit movie 50 Shades of Grey, well then you might want to thank his body double. There's a new report that says the Irish hunk didn't film all of his soft erotic scenes, as his stand-in did most of the work for him on the big screen.

According to Irish Central on Tuesday, Canadian model Peter James Gray worked as Dornan's body double in the last film, although it is uncertain exactly which scenes he did and which ones belonged to Dornan, who played Christian Grey in the hugely popular yet controversial film.

When asked about the film, Gray's spokesperson simply said, "He's now pursuing a serious acting career so I'd prefer to keep emphasis on that."

It is also unknown if Gray will be working as Dornan's body double in the next film, 50 Shades Darker. Although, the same report does indicate that actress Dakota Johnson - who played Anastasia Steele in the movie - had a body double as well.

Meanwhile, the 50 Shades of Grey franchise has hit fever pitch again as E.L. James' latest book, 'Grey: Fifty Shades of Grey as Told By Christian' has sold over one million copies since it debuted last week.

According to Naughty But Nice Rob, fans flocked to their local bookstores to grab a copy of the book, which is apparently told by the Christian Grey character, which is played by actor Jamie Dornan in the big screen adaptation of the first book.

What's more, the book's publisher Vintage is supposedly pushing for third, fourth and fifth printings of the novel with over 2.1 million reprints being delivered daily across the country.
