Nicki Minaj Flaunts Underboob in Billboard Music Awards Dress

We're huge, huge fans of Nicki Minaj's new, back to basics look. If we need any proof that the pared-down look is working for her, we have to look no further than her dress at the 2014 Billboard Music Awards!

The rapper showed off her serious curves in a skintight black Alexander McQueen gown that also included a few risky cutouts! (Just check that hint of underboob.) Never fear -- Nicki looked ultra classy and managed to avoid any hint of a wardrobe malfunction. Yep, girl has high fashion looks down pat.

Although the gown showed a lot of skin, the long column skirt kept things classy. Nicki even added some old-school Hollywood waves. Nope, it's not as loud as some of her previous looks, but we think it's a total win.
