Singer turned actress Rita Ora has reportedly signed on for two more sequels of the erotic film "Fifty Shades of Grey."

The movie version of the first book in the bestselling erotic series of E.L. James may still have to wait for Valentine's Day of next year but one of its cast members has already signed on for the sequel films. Ora will continue playing the role of Mia, the adopted sister of the kinky businessman Christian Grey portrayed by Jamie Dornan, reported Metro.

Many are looking forward to how the 23-year-old singer will do as an actress in such a huge film, considering that it is her first. Aside from the curiosity building up about the singer's ability to act, Ora has also been in good terms with the "Fifty Shades of Grey" movie cast.

Hollywood actress Marcia Gay Harden revealed that Ora and Dornan love singing in between their takes during the shoot of the first movie. Harden plays the role of Christian Grey's mom.

Harden added that the two love singing Ora's songs since the former Calvin Klein male model is a fan of the artist who is now his co-star as well.

Despite recent news that Ora will still be seen in the "Fifty Shades of Grey" sequels, she emphasized that her acting schedule won't get in the way of her career as a singer.

"Music is obviously my main focus in life. But the movie was planned for when I had time to focus on it," Ora explained about her budding music career.

Nevertheless, the "I Will Never Let You Down" singer was humble enough to admit how her acting skills were put to the test in the movie. According to Mirror UK, she admitted to having someone dictate lines to her through an earpiece. She confessed that she got extremely nervous during the shoot that she completely forgot the lines she memorized for the movie.

She also did not forget crediting co-star Dakota Johnson who plays Anastasia Steele, for helping her overcome her fears of being a first time actress.

Ora has once shared that she finished reading all three novels of E.L. James and how proud she is of having been selected to be a part of its cast directed by Sam Taylor-Johnson.

"I think the actors are phenomenal in this and I'm just kind of honored to be on the same wavelength as them," the RIP hitmaker added when asked about the cast which stars Jamie Dornan and Dakota Johnson as the film's lead stars.
