It looks like RocNation's Rita Ora is getting more into the acting scene. If you've seen Fast and Furious 6, you probably caught a quick cameo with her starting off one of the races. Well now, according to Bossip, Rita has been cast in the upcoming movie "Fifty Shades of Grey," based off the best-selling book by the same name. So will she do a walk through or another cameo? Actually, Rita will play the adopted younger sister of the main character, Christian Grey. I haven't read the book, but I've heard it's definitely a steamy one. Congrats to Rita for adding that on her long resume!
