Happy Birthday Leonardo DiCaprio [VIDEO]

It may come as a bit of a shock but Leonardo DiCaprio is pushing 40. Today is Leo's 39th birthday and although he is now one of the biggest movie stars in the world you might remember that he got his big break on the small screen in "Growing Pains" in 1990. Do you remember what he looked like then?

This is how he appeared as Luke Brower in 24 episodes of "Growing Pains" in 1990-1991. He was 16.

And this is how he looked as Jack Dawson in the 1997 blockbuster "Titanic". He was 23.

Here is is in his upcoming movie "Wolf of Wall Street" in theaters December 25.

I'd have to say he is aging gracefully.
