Mariah Carey Debuts Dramatic Weight Loss

She was rumoured to have had a gastric band fitted late last year. And it's either that or Mariah Carey has been at the SlimFast because the once-curvy singer is looking amazing!

Mariah, 48, showed off her dramatic weight loss as she held hands with toyboy Bryan Tanaka ahead of a dinner date in Beverly Hills.

Wearing a knitted black dress that made the most of her nipped-in waist, there wasn't an inch to pinch on the slender star, who by January was already believed to have dropped 2st.

It comes after she reportedly went under the knife last September after being body-shamed during her now-concluded Las Vegas residency.

"Mariah has always been proud of her curves, but this summer, as her Caesars Palace residency came to a close, and then she went on tour with Lionel Richie, she noticed it became harder to dance, and she was getting a lot more criticism online from body shamers.

And sick of endless dieting, Mariah - who loves a slap-up meal and a glass of champers - decided to take more permanent action, a source claimed.

"She always fluctuates and it makes her upset but it's hard for her to manage," the insider told Entertainment Tonight.

"She's happy with this new chapter in her life."
