Mariah Carey flaunted her new weight loss to full effect yesterday on a date night with husband Nick Cannon.

The singer looked younger than her 42 years, flaunting her toned legs in a blue mini dress that also enhanced her boobs. Mariah appeared to coordinate her outfit with Nick's dapper cream and blue suit.

Mariah and Nick, who left one-year-old twins Morrocan and Monroe at home for the night, headed to NYC's Opera Gallery to attend the 2012 Project Canvas Exhibition & Art Gala.

The couple looked like the epitome of bliss, fresh from renewing their vows in Paris last month on their fourth wedding anniversary.

What do you think of Mariah's barely-there dress? Too much?
