The latest addition to the Fifty Shades of Grey cast is truly a surprise. The 23-year-old singer Rita Ora is booked to play the role of Christian Grey's sister.

Huffington Post reports that in the meantime, Rita is bidding goodbye to her singing side to focus more on her major movie project. After releasing an album in 2012, the singer seems to be trying her hand in acting, with the movie side of her resume including the latest installment of Fast & Furious. She also appeared in a 90210 episode.

Rita's character in Fifty Shades of Grey is Mia, a character who was only featured in the first book of the bestselling erotic book series and then returned on the third book. Hence, this just means that the singer-actress can be seen in the full film series adaptation, according to Independent UK.

This just leads to the reality that there is no stopping the release of the erotic film whose premiere date was pushed back to February of 2015. For the past several months, numerous setbacks were faced by the entire film set and crew including the backing out of the first Christian Grey choice, Charlie Hunnam.

Another very interesting Fifty Shades of Grey news include the possibility of another version of the film to be made which will serve as the "dirtier" rendition of the movie. This is something that the film producer Dana Brunetti is highly considering to respond to most fan concerns over Twitter, Hollywood Life stated.
