The LA native kicked off his career 30 years ago, with a behind the scenes tantrum on the now defunct kiddie show Romper Room, and spent his teen years working the TV scene, including stints on the soap Santa Barbara and the sitcom Growing Pains.

DiCaprio's big breakthrough came at 19 with This Boy's Life, his flick with Robert DeNiro and Ellen Barkin. What's Eating Gilbert Grape, which came out the same year, landed him his first Oscar and Golden Globe nominations, and the pretty young thing continued to prove himself with tough roles in The Basketball Diaries and Marvin's Room.

He put Shakespeare back on the map with Romeo & Juliet and it was, of course, his epic flick Titanic that claims the honor of being the highest grossing film ever and pushed him into the $20 million stratosphere.

SheKnows can't possibly mention every movie that's earned him attention, but it's worth noting that the biopic The Aviator won him his first Golden Globe and his second Oscar nom, while officially bumping him into the Leading Role category.

A story making rounds on the net claims he just dropped $1,400 on beauty products geared at anti aging and while his rep says they were a gift for someone else, SheKnows reminds you that we've seen how the years may treat his famous mug. We got a sneak peak in Revolutionary Road, which was not overly kind in the makeup department, and he looked good to us!

He's maintained onscreen credibility by starring in big hits that stretch his talents with characters ranging from romantic leads to megalomaniac businessmen, and now he's promising to scare us silly with Martin Scorsese's upcoming Shutter Island, due out in 2010, and Inception, a Christopher Nolan sci-fi thriller currently in the works.

He's also managed to balance his rep for dating hotties like Gisele Bundchen and Bar Refaeli with his efforts to save the world. In 2007, he produced, co-wrote and narrated the documentary The 11th Hour, and half of his official website is devoted to his commitment to the environment.

Leo celebrated last night at Villa and then at home, with a host of big names. No word on whether childhood pals Tobey Maguire, Lukas Haas and Kevin Connelly were on-hand, but cameras did catch Lindsay Lohan and Ryan Phillippe making their (separate) exits.

This has of course led to speculation about Leo and LiLo… but we won't go there today.

Instead, SheKnows raises our flutes to wish him a happy birthday. We can’t wait to see what the next 35 bring for the king of Hollywood!
