Dornan sang Ora on 50 Shades set
Jamie Dornan took to singing Rita Ora tracks in between takes while shooting the F ifty Shades Of Grey film.
How We Do (Party) singer Rita plays Christian Grey's sister in the film adaptation of EL James' best-selling novel.
US actress Marcia Gay Harden , who has been cast as Christian's mother Grace, said Northern Irish actor Jamie - who stars as Christian - is a fan of Rita's songs.
She told Entertainment Weekly Radio: "Behind the scenes, he'll jump into an Irish ditty, or he was singing a lot of Rita Ora.
"He's like [in Irish brogue], 'Oh, you got that in [my] brain now.' We're like, 'Come back to America, because you got a scene in a minute.' 'But it's in my brain!' He's sweet."
She said of her role: "I play Mama Grey, so it's like, unless you're in the red playroom with a toy in your hand and naked flesh in your face, it's sort of like any other movie that you could do. I throw the dinner parties. 'Hello, let's sit down to dinner.'
"But the story is so intriguing, and I think so many people have read it, and it is erotic... I like looking and thinking, 'Why did we anthropologically select for erotic pleasure in pain?' It's really interesting to me. And EL James has the answer."
