The Fifty Shades of Grey movie has added a new member to its sexy cast: singer Rita Ora.

Ora will play Mia, the adopted sister of Christian Grey (played by Jamie Dornan), Variety reports.

"It's official! I've been cast in @FiftyShades of Grey as Christian's sister Mia. #FiftyShades," Ora said via Twitter.

Ora is best known for her budding music career. The British singer-songwriter is currently signed to Jay-Z's Roc Nation label. Her first album, Ora, was released last year and went platinum, Rolling Stone reports. According to The Hollywood Reporter, Ora has had three consecutive No. 1 singles, including "Hot Right Now." Ora went on her U.K. Radioactive Tour in January of 2013. Since then, Ora has been making her self known at various music festivals and is also working on her second album.

Ora joins a Fifty Shades of Grey cast that is looking more solid since the departure of Charlie Hunnam as Christian Grey on Oct. 12. Dakota Johnson happily accepted the lead female role of Anastasia Steele. Max Martini recently joined the cast as Jason Taylor, Christian's bodyguard. Eloise Mumford will play Kate Kavanagh, Anastasia's roommate. "Pride and Prejudice's" Jennifer Ehle is Anastasia's mother. Meanwhile, Victor Rasuk has been cast as Jose, a photographer who dreams of making romantic Kodak moments with Anastasia, and Luke Grimes will play Elliot, Christian's brother.

Sam Taylor-Johnson is the director of the Focus Features and Universal Pictures movie. Michael De Luca, Dana Brunetti and E.L. James, the author of the erotic novel from which the movie is based, are producers.

Production for the film began yesterday in Vancouver, Canada. (The Fifty Shades of Grey novel takes place just south of Seattle, Washington.) Various photos snapped by paparazzi showed Dornan dressed in Christian Grey style, like the true kinky, wealthy, sex fiend he is. The "Once Upon a Time" actor was seen in a black three-piece suit with a flashy timepiece on his wrist. Meanwhile, Johnson morphed into Anastasia Steele, the naïve college student who falls for Christian's sadomasochism. The 21 Jump Street actress wore an army-green denim jacket, fashionable scarves and, of course, her newly brunette hair.

Fifty Shades of Grey will be released just in time for Valentine's Day on Feb. 13, 2015.
