To celebrate his 37th birthday on the numerically awesome date of 11/11/11, Leonardo DiCaprio threw a star-studded bash at New York City hotspot, "Avenue." Celebs in attendance included Russell Simmons, Robert De Niro, Edward Norton, Bradley Cooper (People's recently announced "Sexiest Man Alive") and, naturally, some Victoria's Secret and Brazilian supermodels. 


A source told People magazine that Leo "was having a great time and talked to everyone at the party."


Never one to miss an opportunity to support the causes he's passionate about, DiCaprio also turned the party into a fundraiser by adding substantial fees to all drinks and bottles of champagne. According to the NY Post, one custom-painted bottle of Veuve Clicquot by artist Peter Tunney sold for a whopping $50,000!


The final total raised, which will benefit the Leonardo DiCaprio Foundation, was just over $1.3 million. According to People, the cash will support environmental initiatives, as well as rebuilding projects in Haiti (likely in partnership with close friend Sean Penn).


At a recent press conference for his new film "J. Edgar," DiCaprio talked with MNN about his early appreciation for the environment and his current focus to save the last remaining wild populations of tigers.


"I was fascinated with nature and I actually wanted to be a marine biologist when I was very young and that was a great passion of mine," he said. "In the off-season when I'm not making movies, I became more and more active as an environmentalist and trying to be more vocal about issues that I felt were important. I created my foundation as a result of that and throughout my website, I try to shed some light on some very topical issues."


"Right now the campaign that I'm a part of is to save the last remaining wild tigers throughout Asia. There are only 3,200 left in the wild. There are more tigers in Texas in cages than there are tigers in the wild and we're at risk of losing this iconic species for all time."
