Happy 35th Birthday, Leonardo DiCaprio!

Leonardo DiCaprio turns 35 today and to celebrate the milestone we put together this slideshow of some of Leo's biggest moments! He's been in show business for almost 20 years and has grown up so much along the way. From his best friends like Tobey Maguire, Lukas Haas and Kevin Connelly to his bikini-loving model girlfriends like Gisele Bundchen and Bar Refaeli, Leonardo has gone from heartthrob to leading man. He's still the star of the highest grossing movie of all time, Titanic, but he also makes time for his passions in life, like the environment as well as the most important people, like his mom. Happy B-day, Leo! View Slideshow ›
