It's official - Jamie Dornan is the new Christian Grey in the "Fifty Shades" movie.

"Stow your twitchy palms ladies… our man is here. Welcome to #TeamFifty @JamieDornan1 x," E. L. James tweeted yesterday.

Dornan, 31, is a former Calvin Klein model and "Once Upon a Time" actor. Reports started to surface midweek that he would replace Charlie Hunnam after the "Sons of Anarchy" star dropped out of the film due to a busy schedule.

The studio declined to confirm the casting, but the author's tweet seals the deal.

And she tweeted when Charlie Hunnam was cast and even when he left the project.

"I wish Charlie all the best. x," she posted.
