E.L. James Confirms Jamie Dornan For 'Fifty Shades Of Grey,' Fans Say Squeeeeeeeeeeeee!!!!!'

'Stow your twitchy palms ladies ... Our man is here,' says James.

She's said it before, but this time E.L. James means it: Christian Grey is locked down. The "Fifty Shades of Grey" author confirmed the news on Thursday, tweeting her excitement about the casting of Jamie Dornan
 in the big screen adaptation of her wildly popular erotic novel.

"Stow your twitchy palms ladies ... Our man is here," she said. "Welcome to #TeamFifty @JamieDornan1 x."

The response was immediate, and twitch-free. "Squeeeeeeeeeeeee!!!!! Good choice my lady !!! You did good :)" raved one fan. Another said, "Yea! You made me pull over on the highway!"

Others deemed Dornan either a "great choice" or "perfect" for the role, while Susan McCaskill got into character for her tweet. "I just got the shivers!!!," she wrote. "I need a safe word to deal with this!! Yay!!"

The 31-year-old "Once Upon a Time" actor steps into the shoes of Charlie Hunnam,
 the "Sons of Anarchy" star who dropped out of the lead in the film less than a month after accepting the highly sought-after role.

In addition to James' endorsement, Dornan seemingly got the thumbs-up from one of the most important people involved in "Grey": his co-star, Dakota Johnson, 24. The actress who will portray Anastasia Steele got high praise from one of the film's producers, Michael De Luca, who told E! News earlier this week that she is, "The best partner a producer could have."

Before Dornan's casting was announced, De Luca said Johnson's "chemistry test" with her potential on-screen co-star was crucial to the process. "She's helping us look through the candidates to see which chemistry kind of captures our attention," he said. Despite what Dornan told MTV News back in October 2011 about how he gets "nervous" around the ladies,
 clearly she and Dornan ended up finding the right mix.
