Despite uttering only four lines of dialogue in the first Fifty Shades of Grey instalment, Rita Ora has secured herself a role in the second and third instalments of the raunchy trilogy.

The British singer took on the role of Mr Grey’s sister Mia in the much anticipated movie adaptation of E. L. James’ book that was released in February.

According to Sony Pictures emails that were leaked and have subsequently appeared on Wikileaks, the 23-year-old will reprise Mia Grey’s character for the second and third movies.

In an email seen late last week, Rita’s US agent, Franklin Latt, wrote to former Sony Pictures CEO Amy Pascal and said: "Rita will appear in Universal’s upcoming Fifty Shades of Grey playing the role of "Mia Grey" and will appear in the next two instalments of the movie."

Rita’s role only lasted for 90 seconds in the first film and the star was criticised for her small cameo.

Although Rita seems to be a dead cert for the next two movies, the Fifty Shades franchise has been plagued by departures with director Sam Taylor-Johnson and screenwriter Kelly Marcel not returning to the follow-up projects.

After reported clashes between the directing and writing team and the books’ novelist, plans for E. L. James to pen the next screenplay herself have been suggested.
