In the past year, we've grown accustomed to seeing boy beauty Leonardo DiCaprio become a free-spirited Citi Bike rider and an e-cigarette enthusiast. In rare moments, he's even juggled both of his newly acquired hobbies at the same time. Today, Leonardo (or Romeo, Jack, Cobb, Jay, or whatever you call him) turned 39 years old. But before you have a panic attack wondering where time has gone, celebrate this actor's existence by reveling in his birthday festivities: He stayed out until 4 a.m. at Tao in the company of 2 Chainz (who called him "Brother Leo"), Kanye West, Tobey Maguire, Derek Jeter, Martin Scorsese, and more. See him celebrating here — or just imagine that he spent all evening doing the impressive dance move below.
