The 23-year-old "Hot Right Now" singer will play Mia, the bubbly, adoptive sister of the titular character Christian Grey, according to Variety. (Think Ashley Green's Alice Cullen in "The Twilight Saga.")

Director Sam Taylor-Johnson and the crew began shooting in Vancouver on Sunday and Dakota Johnson was seen filming a scene in a coffee shop, Us Weekly reported.
The release date has been pushed back, Movies Now said, from August 2014 to a Valentine's Day-oriented release date of Feb. 13, 2015, which has raised concerns about the film losing its appeal the further its release date gets from the height of the books' popularity.
