"Fifty Shades of Grey" star Jamie Dornan revealed that despite his sexy role as Christian Grey, he still feels like the "skinny kid" he was in his childhood. Though Jamie Dornan had to spend most of his time on the "Fifty Shades of Grey" movie set in a suit, he says he still doesn't feel comfortable in Christian Grey's wardrobe.

"I don't like my physique. Who does? I was a skinny guy growing up, and I still feel like that same skinny kid," "Fifty Shades of Grey" star Jamie Dornan admitted to Interview magazine in their June 2014 issue, ET News reports.

Jamie Dornan, 32, also says he feels "awkward" in a suit, which he had to wear almost everyday on set in his role as successful businessman Christian Grey.

"I think there was so much more to Christian that we covered -- someone who is careful to keep himself in shape, someone who spends obscene amounts of money on presenting himself. A lot of that work was done in the gym and with costume. We didn't talk about particulars of the way he would move," Dornan said about his character. "But I'm quite awkward in a suit because I don't have an opportunity to wear a suit very often, and this is a guy who lives in a suit -- the best suit. That has to have an effect. But when you end up in a suit for 80 percent of the filming process, you become pretty comfortable with it."

We can't imagine someone as handsome as Jamie having body image problems, but perhaps it just goes to show that anyone can be insecure - no matter how big your biceps are.

Meanwhile, as we previously reported, "Fifty Shades of Grey" movie director Sam Taylor-Johnson purposefully didn't cast her husband and "Godzilla" star Aaron Taylor-Johnson in the coveted role of Christian Grey.

"I think it would have been the wrong kind of hype to bring toward us," the 23-year-old says in Nylon Guys' May 2014 issue, E! News reports. "It would have been kind of funny that this character that all these women fancy-he's one in a million-and my wife picks her husband to play the part? I would love to have done something together again, but it wouldn't have been 'Fifty.' We were both on the same page."

In fact, Aaron Taylor-Johnson hasn't even read the book!

"I'll watch the movie, though!" he added.

The "Fifty Shades of Grey" movie is scheduled to release on February 14, 2015. Dakota Johnson will co-star as Anastasia Steele.
