Zach Galifianakis Reveals Shocking Weight Loss

The "Hangover" star looked considerably thinner at a recent event in NYC.

Zach Galifianakis, is that you?

The "Hangover" star, 45, appeared considerably thinner at an event in New York City on Oct. 11 and joked to E! News that he's "dying." (His new size? A "ladies 50.")

However, his weight loss has been a gradual thing for Galifianakis. Last year, he told Conan O'Brien that after he quit drinking, the pounds began to fall away.

"I was having a lot of vodka with sausage," he told the comedian. "Delicious but bad for you!"
