Who saw this coming? In the most surprising casting news in a long while, Rita Ora has confirmed via her Twitter account that she is joining the cast of the Fifty Shades of Grey movie. What?

It's true! And she's not even doing one of those cameos as a singer in a nightclub or something, nope, she is to play Christian Grey's sister Mia.

It turns out that Rita is in fact an actress, kind of. She went to the (in)famous Sylvia Young Fame Conveyor Belt Stage School, whose notable alumni include Jodi Albert, Billie Piper and Amy Winehouse. She also made a blink and you'll miss it appearance in Fast & Furious 6.

Fifty Shades will be directed by Nowhere Boys' Sam Taylor-Johnson and will star Jamie Dornan as Christian Grey and Dakota Johnson as his prey Anastasia Steele.
