MUMBAI: Singer-actress Rita Ora, who stars in the film adaptation of author E.L. James' novel 'Fifty Shades of Grey', says she's the "biggest fan" of all three books.

The 24-year-old, who essays the role of Mia Grey in the film, says she has all three books of James' novels including the follow-ups – 'Fifty Shades Darker’ and 'Fifty Shades Freed’, reports femalefirst.co.uk.

"I have all three books, I'm one of their biggest fans. In the first book, my character really isn't in it that much," Ora told Capital FM.

"I always have been asked, 'can you do a mini cameo?' It's never been like a supporting role. And I thought why not be a part of the biggest thing that's about to come out in 2015, regardless if it's 10 seconds or 90 seconds," she added.

Although, Ora only has three lines in the movie, she believes that appearing in such a high-profile film will create more acting opportunities for her in the future.

Asked to recreate her American accent in the film, she said, "No! I'm actually speaking French in that movie! Honestly, I don't want you guys to over-talk about it, because it's just a little second, alright? It gave me a lot of opportunities for other Hollywood things."
