E L James has finally locked down her on-screen Anastasia Steele and Christian Grey.
The 50 Shades of Grey author announced the news Monday morning, tweeting that Dakota Johnson and Charlie Hunnam have been cast to play the coveted roles in the film adaptation of her erotic love story.
"I am delighted to let you know that the lovely Dakota Johnson has agreed to be our Anastasia in the film adaptation of Fifty Shades of Grey," James wrote, later adding, "The gorgeous and talented Charlie Hunnam will be Christian Grey in the film adaptation of Fifty Shades of Grey."
Dakota, who is the daughter of Don Johnson and Melanie Griffith, is best known for her starring role on the now-defunct Fox sitcom Ben & Kate.
The actress has also had roles in The Five-Year Engagement and 21 Jump Street, and most recently teamed up with Penn Badgley and Ethan Hawke to star in the Shakespeare drama Cymbeline, which is currently filming in New York.
Hunnam, who stars on Sons of Anarchy as Jax Teller, has also had previous roles in Pacific Rim and Deadfall.
