Rita Ora believes the upcoming 50 Shades of Grey movie will be a "passionate" affair.

The singer has a role in the film version of the bestselling E.L. James erotic novel, which infamously flirted with themes of bondage and S&M.

She has filmed parts for the Universal Pictures flick in Toronto and the 'Radioactive' star told Capital FM that it is set to be a "passionate" affair.

Ora said: "The movie is amazing, it's such a great passionate movie. I had to be involved, I love the books.

"I know everybody's going to watch it, whether it's in secret or confidence, but everyone's going to watch it," she explained. "It's going to be fun. I look really different and it was a good experience."

The singer meanwhile recently said that she would most likely contribute music to the film's soundtrack.
