In celebration of the Ryan Reynolds's 37th birthday, here are seven things that you probably didn't know about him!

1. The birthday boy's wax figure was unveiled today at Madame Tussauds Hollywood. They both looked fine in matching three-piece suits. 

2. He's the youngest of four boys. The sexy Scorpio revealed in an interview that he and his beautiful wife Blake Lively would love to have a big family of their own. 

3. Like many Hollywood actors, this Canadian-born cutie failed his high school drama class. For someone who's had no formal training, he's had quite the career. 

4. The 'Selfless' star rescued the retriever-mix back in 2009. His four legged-friend named Baxter is one lucky dog! 

5. While skydiving for the first time, the then 17-year-old's parachute failed to open. He hasn't been skydiving since.  

6. In 2008, he published "Why I'm Running the New York City Marathon" in Huffington Post. He can act and write? Swoon! 

7. He held the title of People's Sexiest Man Alive in 2010. Okay, so if you're a true Ryan fan you probably already knew this...but we couldn't help but mention it.
