Mariah Carey is working hard to get her infamous body back and it’s paying off. The singer has now lost ANOTHER 20 lbs. and is looking slimmer than she has in years. The 20 lbs. is in addition to the 40 lbs. she had already lost earlier this summer. Although the singer reportedly underwent gastric bypass surgery last November, she’s also been working with a personal trainer and a nutritionist to help get the body she wants, which includes cutting out carbs and sugar… besides wine, of course.
