mariah nip slip

*One outlet called it “The Emancipation of Mimi’s Nipple.”

Mariah Carey had a tiny little nip slip at So So Def’s 20th Anniversary Concert on Saturday (Feb. 23) at Atlanta’s Fox Theatre that is just now making the rounds online.

She took the stage to wheel out a birthday cake for So So Def’s founder and longtime collaborator Jermaine Dupri.

Unbeknownst to her, Carey’s left nipple peeked briefly out of her dress as she waved to fans onstage.
