Last night, Rita Ora attended the British Fashion Awards in a liquid silver gown by Vivienne Westwood looking the picture of Hollywood glamour before taking to Twitter to announce her role in the upcoming film adaptation of EJ James’ bestselling novel:
‘It's official! I've been cast in @FiftyShades of Grey as Christian's sister Mia. #FiftyShades’
This will be Rita’s biggest role to date (she previously starred in Fast and Furious 6). Like good friend Cara Delevingne - who was notably absent from the British Fashion Awards last night - Rita seems keen to add a string of movie credits to her CV.
But Rita didn’t appear to be missing Cara last night: we spotted her laughing and posing on the red carpet with Kate Moss and she presented Nicholas Kirkwood with the award for Accessory Designer of the Year.
Filming for Fifty Shades has already begun so we expect Rita will join Dakota Johnson (Anastasia Steele), Jamie Dornan (Christian Grey) and Sam Taylor-Wood (director) on set soon ahead of the film’s 2015 release.
