![Nicki Minaj: Nicki suffered a similar fate to J.Lo when she almost had her nipples on show during a concert in Manchester a few days ago. Luckily, the star had her modesty preserved by two flowery nipple covers. She's probably learned from her 2011 experience - at a Good Morning America performance, she had a nipple slip with nothing underneath. Oops!]()

![Beyonce: At the Oscars, Beyonce did a great song and dance number with Hugh Jackman. However, she was redfaced when, during a dip, her glittery corset top slid down and exposed the tiniest bit of nipple.
