It didn't take long for the SAG Awards to offer up its first shocking moment!
Within the first five minutes, funnyman Zach Galifianakis appeared on screen looking nothing like his former self after undergoing a massive weight loss.

The 'Hangover' star first made headlines last fall over his noticeably slimmer figure, but it looks like the 45-year-old just keeps losing more and more!

Though he may have shed some pounds, Zach thankfully didn't lose his sense of humor, making the SAG audience laugh on more than one occasion.
"I'm Zach Galifianakis, and I'm an...actor?" he hilariously recited during the show's infamous opening monologues.
While promoting his award-winning film 'Birdman,' the star previously joked about his transformation, "[I lost] about 30 ounces. I started walking a bunch and gave up booze. Booze, I was done with it. I couldn't wake up [like usual], so I stopped. I'm lucky that I could just stop, but boy I miss it."
He told WGN, "Being light is fun. I can go up two flights of steps now, and only need my inhaler twice."
