We've seen it before with Jonah Hill and Chris Pratt, but this time it was Zach Galifianakis' turn to wow heads after an extremely impressive weight loss transformation.
Arriving on the red carpet of the 69th Primetime Emmy Awards, the former Hangover star showed off a much slimmer build in a fitted tux.
In 2013, the 47-year-old told Conan O'Brien he needed to address his health: "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."
Despite looking the part, Galifianakis wasn't able to take home the award for outstanding lead actor for his role in the comedy Baskets.
