British pop singer-turned-actress Rita Ora has been discussing her role in the upcoming film adaption of ‘Fifty Shades of Grey’.

The ‘RIP’ star revealed that she had landed the role of Christian Grey’s sister Mia back in December.

Ora previously made an on-screen appearance in ‘Fast & Furious 6’ as a racer but was in a non-speaking role.

Whilst attending Roc Nation’s pre-Grammy brunch yesterday (January 25), Rita spoke to MTV about her big screen nerves.

Ora said: “Oh, I was nervous because it was the first time I ever did a movie with words.”

She added: “But it was so nice. The director Sam [Taylor-Wood], she was incredible, so it was all love.”

23-year-old Rita promised reporters that the film will be “the biggest and most amazing shock ever”.

Aside from acting, the ‘Radioactive’ songstress gave away some details about her forthcoming second album as she stated:

“It comes out in a few months. It's been about a year and a half of kind of doing it undercover, but I can officially say it's done. The album's gonna be great.”
