"Fifty Shades of Grey" cast member Rita Ora is set to join the new movie's upcoming sequel after her huge fan, director Sam Taylor-Johnson, decided to quit the raunchy trilogy. Rumors also have it that Calvin Harris' ex-girlfriend will crack Hollywood with her upcoming roles.

In a report by Mirror UK, it was said that Sony Pictures emails released by Wikileaks revealed that the "I Will Never Let You Down" singer will have a secured spot in the cast, reprising her role as Christian Grey's sister Mia.

The e-mail sent by her agent Franklin Latt said, "Rita, 23, 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."

Reportedly, Rita Ora is still eager to pursue her role even if "Fifty Shades of Grey" director Sam Taylor-Johnson decided to quit the movie due to conflict with book writer E.L James.

Sam Taylor-Johnson was very vocal in saying that she is a big fan of the "Black Widow" singer, Simcoe.com said.

Rita Ora recently gained flak for her role in "Fifty Shades of Grey" when she was shown with only four lines in less than five minutes.

But the "How We Do" singer quickly came to her defense and said, "Everyone is going to have their own opinions."

The Kosovo-born singer even added, "But for me this was such a great cameo to be involved in, and even though I'm only in it for a little bit, it's opened the door to a lot of movie things that I haven't actually announced yet.

The British singer is slowly gaining fame worldwide after she clinched a number of endorsements from top brands including Adidas and Roberto Cavalli. The fact that she also songs at the top of the charts made her even more known.
