Looks like we've finally got our Christian and Anastasia!

50 Shades of Grey author E.L. James announced via Twitter Monday that "Sons of Anarchy" star Charlie Hunnam and Dakota Johnson have been cast in those highly-coveted roles.

"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," tweeted James. "The gorgeous and talented Charlie Hunnam will be Christian Grey in the film adaptation of Fifty Shades of Grey."

Johnson, who most recently starred on the now-canceled Fox sitcom "Ben & Kate", is the daughter of actors Don Johnson and Melanie Griffith.
