Rihanna flashes her bum in low cut gold gown at Met Gala afterparty
Bum alert She may have been photobombed by BFF Queen Delevingne on the red carpet . But Rihanna well and truly stole the show when she showed off her builders' bum at the Up & Down nightclub in New York on Monday. The Pour it Up singer flashed her bottom-cleavage (yep, really, on purpose) in a low slung gold bum-baring gown which left very little to the imagination. It seems since her Vogue shoot Ri-Ri has become increasingly comfortable showing off her naked body , because she gave the world a real eyeful in her sparkly number.
