Melissa McCarthy always looks incredible... but she's looking a tad different to how she used to!

The hilarious actress has been out and about promoting her upcoming film, Life of the Party, while also showing off her amazing body transformation.

Sharing multiple images from the movie on Instagram, the 'Bridesmaid' star shocked fans with her much slimmer face.

Beginning her journey to a healthier lifestyle back in 2015, the 47-year-old has reportedly since dropped more than 34.5kg!

According to the Daily Mail, Melissa has been following a low-carb, high-fat, and moderate-protein diet, known as the ketogenic diet.

Speaking to Redbook Magazine the mother-of-two said: “My message is that as long as everybody’s healthy, enjoy and embrace whatever body type you have. There’s an epidemic in our country of girls and women feeling bad about themselves based on what .5 per cent of the human race looks like."

Life of the Party is a comedy film about a mother heading back to college after the breakdown of her marriage.

It's scheduled to be released on May 11, 2018.
