Rapper Nicki Minaj suffered another wardrobe malfunction on Tuesday (15Oct13) after accidentally exposing her nipple at the Los Angeles launch of her new fashion collection.

The Starships hitmaker went bra-less and shirtless in a cobalt blue blazer as she unveiled her clothing line at U.S. department store Kmart, but she struggled to keep her breasts fully under wraps and bared more than intended as she posed for cameras on the red carpet.

Minaj, who is known for her dislike of undergarments, is no stranger to nip-slips - she flashed her boob last month (Sep13) after donning a cropped black jacket with nothing underneath for an appearance on America's The Ellen DeGeneres Show.
