Mariah Carey suffers wardrobe malfunction with strapless dress 'nip slip'

Mariah Carey favors low-cut attire for her wardrobe as a judge on "American Idol," but the superstar singer might have gone too far this weekend at a So So Def All-Star 20th anniversary concert in Atlanta, Ga.

Photos of the 42-year-old on stage at the party show her left breast popping slightly out of her form-fitting cream dress.

Carey was there to honor her friend Jermaine Dupri with a surprise birthday cake. Jay-Z, Usher and Ludacris were also featured performers at the event.
