Pop star Rita Ora has revealed why she may have landed her part in steamy novel-turned-movie Fifty Shades of Grey.

Cara Delevingne’s pal, who plays Mia Grey, the sister of super-hot businessman Christian, has now said she doesn’t mind the odd bit of alternative action between the sheets.

Rita admitted to enjoying a bit of kinky behaviour in the bedroom with DJ boyfriend Calvin Harris saying, ”I mean, I like a whip. This is why Fifty Shades is perfect for me because I really love the book. But I like unexpected stuff. A tiny bit of [pain], not too much.”

The 23-year-old singer also revealed she is looking forward to taking a long break with boyfriend Calvin in the near future and thinks they’re ”ready” for a holiday together.

She added, ”I think [he’s] ready for us to go away together, I haven’t been away with him in a long time. I want to take my weave out, so it will be nice to spend some quality time.”
