Heartthrob Leonardo DiCaprio celebrated his 37th birthday this past Friday at hotspot Avenue. It seems like just yesterday he was 23 years old and stealing everyone's hearts in Titanic. Oh, how the time flies. In typical alturistic Leo fashion, he donated proceeds (some $1.3 million) of the party to his non-profit, The Leonard DiCaprio Foundation. The foundation funds protection projects for wildlife as well as clean water and disaster relief in third world countries. By adding fees to drinks and bottle services he was able to collect funds from the well-endowed crowd that included billionaires Stewart Rahr and Len Blavatnik along with a slew of Hollywood heavy hitters such as Benicio Del Toro, Robert DeNiro, Naomi Campbell and Ed Norton. Additionally he auctioned items off, which included a 15 liter bottle of Veuve Cliquot painted by Peter Tunney. The bottle sold for a whopping $50,000! 

On the party front, Mark Ronson and Q-tip kept the crowd dancing with non-stop beats while Leo surrounded himself with Victoria's Secret supermodels including Alessandra Ambrosio, Izabel Goulart and Ana Beatriz Barros. Oh, did we mention his mom was also there? Good times!

Happy Birthday Leo! You don't look a day over smoking hot!
