50 Shades Darker filming continues on luxury yacht, after Dakota Johnson admits sex scenes are 'tedious'

Dakota and her co-star Jamie Dornan can be seen laughing on set as they work on the highly-anticipated sequel to the erotic blockbuster

Filming has continued for 50 Shades Darker, as Jamie Dornan and Dakota Johnsonspend some time on a luxury yacht.

The two co-stars looked relaxed as they laughed on set, then snuggled up as they shot new scenes for the raunchy sequel.

The upcoming film - the follow-up to 2014's blockbuster 50 Shades of Grey - is the second adaptation from E.L. James' erotic thriller, and work is well under way on the movie.

The stars were dressed up for the shoot, with Jamie - who plays kinky millionaire Christian Grey in the franchise - seen in a sharp black tuxedo.

Meanwhile, Dakota - reprising her role as Anastasia Steele - was snapped in a flowing, glamorous silver dress.

She told Interview magazine: "I'm filming the next two instalments of the Fifty Shades movies back-to-back. I'm doing one [of the sex scenes] today. It's not ... comfortable. It's pretty tedious.

"We're not having actual sex. But I've been simulating sex for seven hours straight right now, and I'm over it."
