Instagram just got a whole lot sexier.

Jamie Dornan, the 32-year-old actor who will play handsome billionaire Christian Grey in the upcoming "Fifty Shades of Grey" movie, officially joined Instagram Monday. In his first picture, the actor posted a selfie showing off his beard while holding a sign that reads, "I am Spartacus Jamie Dornan x."

Since signing up on the social media photo-sharing site, Dornan, who goes by the handle @jamiedornan, has gained more than 155,000 followers. His first and only picture has received more than 33,000 likes from his fans.

Fans have been responding well to the photo - @Erisvaniac wrote, "Perfect man!!!! I love you Dornan," while @laisbardinialvesfelippe commented, "Hi 50 shades!!! You are the most sexiest man all the world."

Dornan posted the picture link on his Twitter page, which made it his first tweet since March 28.

The actor will soon be busy promoting "Fifty Shades of Grey" alongside co-star Dakota Johnson. The novel-turned- movie is set to release Valentine's Day of 2015. 

During a Q&A at DBA in Hollywood for the "An Evening in the Writer's Room" series hosted by Reza Aslan earlier this month, screenwriter Kelly Marcel told E! Online that Dornan's performance in the movie is Oscar-worthy.

Marcel joked about his performance by referencing to a line in the novel in which Anastasia Steele says, "He's my own Christian Grey-flavored popsicle." 

Adding: "That line went in, it's genius. They apparently did that scene great. Apparently Jamie is great at being soft and hard at the same time. Which is hard to do for an actor! He's going to get an Oscar!"
