When Melissa McCarthy stepped out on the red carpet at tonight's People's Choice Awards, we were stunned to say the least.

In recent months, everyone has been talking about the actress' noticeable weight loss, and tonight all her hard work was on display in a fitted pair of black pants, a leather-accented top and Forevermark diamonds.

And the actress, who lost approximately 45 lbs., had reason to celebrate right off the bat! She won the first award of the night for Best Comedic Movie Actress and is also nominated for Favorite Movie Actress and Favorite Comedic TV Actress!

Congrats on both your trophy and your weight loss, Melissa!
