Jamie Dornan looks sizzling hot as Christian Grey in the upcoming movie version of the controversial novel "Fifty Shades of Grey." All eyes are now on the Northern Irish heartthrob as he brings the hot business magnate's character to life on the big screen.

Just who is this new hunk on the block? Cinemablend.com shares four juicy facts about Jamie Dornan aka Christian Grey:

1. He does not only look good, but he can sing quite well, too. Jamie Dornan who plays Christian Grey used to be a member of a folk band called Sons of Jim. The group split up in 2008. Prior to the separation, they have had their fair share of success.

2. He and British actress Keira Knightley used to be an item. The couple made the media rounds as a pair back in 2003-2005. Dating Keira gave him a taste of what it was like have the paparazzi tailing him nearly 24/7 - and he did not like it one bit. He clearly recalled how the press gave them a hard time during their two years together.

3. He modeled Calvin Kline clothes and comfortable undies before signing up as an actor for the wildly popular novel that sold 90 million copies. During his modeling heydays, which he admitted he did not enjoy as much, he already donned that distinct clean, shaven look of the would-be Christian Grey. Jezebel.com argued that he looked better with all his (body and face) hair on (moustache, beard, etc.). But the fashion execs who picked him thought otherwise. Besides, to play the role of Christian Grey, he had to strip them off.

4. He had his big break on the screen as Count Axel von Fersen in Sofia Copolla's "Marie Antoinette."Jamie Dornan, who portrays Christian Grey, appeared in the movie alongside Kirsten Dunst in 2006. As Count Axel, he portrayed the role of the French love interest of the queen. The movie hit it big; generating a strong cult following that lasted almost 10 years after its release.
