Happy 39th birthday Leonardo DiCaprio! Ever since his Growing Pains days as Luke Brower in 1991, DiCaprio has captured our hearts on the silver screen and has since then transformed into the award-winning actor and producer we know and love today. Looking back, who could forget his memorable onscreen roles as Romeo in 1996's Romeo + Juliet, Titanic's heartthrob Jack (we'll never let go!), the suave "pilot" in Catch Me If You Can, to his recent role as Jay Gatsby in Baz Luhrmann's The Great Gatsby. “He really was this gifted young man," Luhrmann said to about working with Leo on Romeo + Juliet and this year's The Great Gatsby. "But now he’s at a point where he’s one of the finest players in the world." What's next for DiCaprio? He is starring as the New York stockbroker Jordan Belfort in Martin Scorsese's highly anticipated film, The Wolf of Wall Street out in theaters on December 25th. In honor of Leo's big day, see how much the legendary actor has grown in our gallery!
