The Sun confirmed in late August that Ora, who plays Christian Grey's sister Mia, has signed on for the film adaptations of the sequels to the hit book. "Music is obviously my main focus in life, but the movie was planned for when I had time to focus on it," Ora said.

Ora also said recently that despite acting being a new venture for her, she would have done anything to be in the sexy film.

"Fifty Shades, for me, was a completely different world; I didn't have any beauty rituals because I didn't really know what was going on!" Ora said about playing the character to the Hollywood Reporter.  "I honestly went in there blindfolded, but came out feeling like an actress. I worked among some incredible actors, and just to be part of the phenomenon was enough of a compliment for me - I didn't care if I had one line in the movie!"
