She spent hours wandering up and down the Cote d'Azur beach, flaunting her fabulous figure in a skimpy yellow two-piece bikini as photographers snapped away from a distance, and then she went topless for a sunbathing scene as co-star Jamie Dornan approached for a little movie love and a massage.

The Irishman, who was joined on set by his wife Amelia Warner, made sure his castmate was covered up with a towel whenever they weren't being filmed.

The Fifty Shades pair also climbed on to a jet-ski for another seaside scene.

Dornan also went topless, sporting ripped abs as he messed around in the sea with Johnson.

She portrays naive student Anastasia Steele in the film series, adapted from author E.J. James' bestselling novels. Dornan plays sadistic businessman Christian Grey.

The Fifty Shades of Grey sequel, which also features Kim Basinger, Marcia Gay Harden, and Rita Ora is set to hit cinemas in February (17), while the third and final film of the trilogy, will be released a year later (18).
