Melissa McCarthy has many reasons to celebrate!

Along with completing the 100th episode of her CBS sitcom ‘Mike & Molly,’ the ‘Bridesmaids’ actress continues to show off her impressive weight loss.

Melissa, 44, and co-star, Billy Gardell, 45, celebrated their show’s milestone at the Cicada restaurant in LA on Saturday night.

The brunette beauty opted for an all-black ensemble that featured a deep-cut V-neck collar that helped show off her slimmer body.

In early January, Melissa flaunted her 45-pound weight loss at the People’s Choice Awards, and looked fabulous while doing it!

Nowadays, the full-figured actress has come to love herself at every size! “I could eat healthier, I could drink less. I should be learning another language and working out more, but I’m just always saying, ‘Ah, I could get hit by a bus tomorrow,’” she previously told ‘Rolling Stone.’
