You go, girl!

Mariah Carey stepped out in NYC looking better than ever in a teal dress after her sold-out show at the Beacon Theatre.

The 45-year-old flaunted her weight loss and curves in a form-fitting gown and added some sparkly bling to accessorize her look.

As In Touch previously reported, the mother-of-two appeared to have lost around 20 pounds within the past few months.

Nadia Murdock — a fitness coach who has not worked with the singer — revealed, “It appears that Carey has lost a significant amount of weight in both her mid-section and hips. In the before pictures, it appears that Mariah may be anywhere between 160-165 pounds. With a voluptuous figure, it's easy to look bigger than you are. In the after photos, Carey appears to have lost between 15-20 pounds.”

Well — the songstress has certainly never looked better. Keep it up, Mimi!
