Wardrobe Malfunction: LeAnn Rimes suffers embarrassing nip-slip

LeAnn Rimes suffered an embarrassing wardrobe malfunction at a charity bash in LA this week - when her nipple slipped out of her low-cut top.  

The country star sizzled on the red carpet in a daring loose-fitting black trouser suit.

But she boobed when she decided to go bra-less.

As the singer, 30, leaned to adjust her trouser leg, her right breast made an unexpected cameo - giving other guests an eyeful.
