Fifty Shades Of Grey stars Dakota Johnson and Jamie Dornan have given fans a first look at their characters after posing for a sensual new shot for the cover of U.S magazine Entertainment Weekly. Northern Irish actor Dornan, who replaced Charlie Hunnam as Christian Grey in the film adaptation of E.L. James' erotic bestseller last month (Oct13), glares into the camera while hugging Johnson, who has dyed her blonde hair dark to play sexually adventurous student Anastasia Steele in the film, to his chest. The dramatic cover shot is the first official snap of the couple together. In the accompanying feature, Johnson admits she's working out hard for the project, which has been put back to Valentine's Day (14Feb), 2015, because she says, "I want to look good naked." Dornan, a former Calvin Klein model, admits he's thrilled he eventually landed the coveted role of Grey after initially auditioning for the part and then learning it had been handed to Hunnam. When the Sons of Anarchy star stepped down in September (13), citing scheduling problems, the 31 year old was hoping to get the call to step in. He says, "There was a slight fear, but, beyond anything else, I was really f**king excited." And he adds, "I'm not shocked by it (the sex in the book). It's essential to tell the story. I can't believe films that don't invoke the sexual side of it. So it works for me."
