Zach Galifianakis hit the premiere of his new movie Birdman in New York on Saturday looking pretty svelte, leading him to joke to E!, "I'm dying," before adding that he was wearing a "ladies [size] 50." He started losing weight last year, telling Conan O'Brien, "I stopped drinking and I just kind of put the weight off … I was having a lot of vodka with sausage … delicious but bad for you. I was getting into too much trouble with the drinking, so I just kind of stopped." (For more Galifianakis, click to watch him spank Justin Bieber.)
