Mariah Carey is proud of her weight loss -- and flaunting it on the cover of Shape magazine wearing a teeny bikini!
Sporting bikini bottoms and a summery, striped crop-top, Mimi shows off her hot bod in the May issue.
The 42-year-old, who gave birth to twins in April 2011, has shed 30 lbs since having little Moroccan and Monroe -- thanks, in part, to her deal with Jenny Craig.
Carey is looking great these days and it's clear she's ready for beach season to begin.
