Leave it to RiRi to take showing some skin to a whole new level!
After showing off her toned tummy in a white Stella McCartney crop top and skirt at the 2014 Met Gala, Rihanna changed into a slinky gold dress that featured a very low plunging back.
The "Diamonds" singer went commando at the afterparty, flashing two inches of butt crack as she posed for photos. She even accessorized her derrière with a delicate gold chain.
The brunette beauty did a bit more than just flash us her bum -- she also served up a major dose of sideboob!
While Rihanna had one of the more racy looks of the night, she was right on trend in her two backless ensembles. From Nicole Richie to Kate Bosworth, the style totally took over on the red carpet at the Met Gala!
