Happy 33rd Birthday, Ryan Gosling!

It's Ryan Gosling's birthday — and we can't believe he sang his way into our hearts on the Mickey Mouse Club 20 years ago. We fell in love with him in The Notebook, swooned over his good looks in Crazy, Stupid, Love, and saw his serious side in The Ides of March. What does he have to look forward to this year? Gosling's directorial and writing debut, How To Catch A Monster, is out in 2014 and features a solid roster of stars. Let's all celebrate the actor's big day by admiring a photo of Gosling and his toned abdominal muscles. Happy birthday, Ryan!
