Jamie Dornan and Dakota Johnson both came to fame with the "Fifty Shades of Grey" movie. Now, they are on the headlines again for a different reason.

According to reports Dornan and Johnson were caught cheating on Amelia Warner in Paris, France. The "Fifty Shades Darker" stars were spotted flirting in public.

Celeb Dirty Laundry reported that they were seen very sweet with each other even outside. This has led the fans to speculate about their relationship behind the scenes.

However, their apparent change in relationship might also be due to their onscreen chemistry, and filming of the "Fifty Shades" sequel.

Johnson recently revealed that she's not comfortable with filming the steamy scenes with co-star, Dornan, because it's "pretty tedious," according to a report by Express.

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

Both Johnson and Dornan were unavailable for comments of their alleged relationship, when reached out. So, fans shouldn't believe the rumors unless it has been proven.

Additionally, Johnson has also mentioned that starring in the BDSM film has not helped her romantic life to progress.

She said, "Some people think this is something I'm interested in, in my private life, which is not the case. I'm an actor, I pretend."

Meanwhile, GamenGuide has previously reported that Jamie Dornan and Dakota Johnson have mutually decided to ban Amelia Warner on the "Fifty Shades Darker" set. According to insiders, Warner has been constantly monitoring her husband and hindered the progress of the filming.

Reports also suggest that the British singer was somewhat envious of Dakota Johnson, and was worried over the romantic bed scenes of Dornan and Johnson in the sequel.

Although these rumors could have a basis, Amelia Warner is yet to comment on their relationship. Meanwhile, "Fifty Shades Darker," starring Dakota Johnson and Jamie Dornan, will be released on Feb. 10 next year.
