The gorgeous Northern Irish actor looked, well, gorgeous as he checked out a preview of the 'Second Floor' exhibit in London on Thursday, 11 September.
Jamie was pictured shooting a smouldering look at the camera… apparently unaware that naughty Sam was having some fun behind his back!
Jamie plays the mysterious Christian Grey in the hugely anticipated movie based on E.L. James' novel of the same name.
Christian is a billionaire businessman with a taste for bondage in the bedroom – something he wants to get courtesy of naïve publishing graduate Anastasia Steele, played by Dakota Johnson.
The trailer for the steamy movie was released earlier this summer and had us ALL talking. Shame we have to wait until Valentine's Day next year for the actual film!
In the meantime, Jamie has been busy teasing us all with what to expect from the movie.
"You've got to make something a large amount of people can go and see. It's not going to be grotesque," he told GQ. "I mean, in some ways, it'll break a few boundaries. But at the same time, they want to put bums on seats. They can't alienate an audience. You know it has to be watchable. It can't be hardcore. I wouldn't have signed up for it if it was."
Jamie was recently named 'Vertu Breakthrough Artist of the Year' at the GQ Men of the Year Awards 2014.
