Mariah Carey is back .... along with her fabulously svelte bod!

The 42-year-old diva debuted her latest music video for the single "Triumphant (Get 'Em)" featuring Meek Mill and Rick Ross.

Dressed in a skintight gold mini, Mimi looks better than ever. Hubby Nick Cannon directed the video which is centered around a boxing match.

Put up your dukes because Ms. Carey is gonna be fighting to make her way to the top of the charts once again!
