Rihanna Shows Her Butt Crack In Met Gala 2014 After-Party Dress

Rihanna's party outfits are sizzlin' but her after-party dresses are even hotter.

After turning heads in a daring white Stella McCartney ensemble at the 2014 Met Gala on Monday night, the singer changed into something more comfortable: a slinky gold metallic backless dress (also Stella McCartney) that showed her butt crack when she turned around!

Where does one wear such a racy dress? At RiRi's Met Ball after-party of course, which she hosted at Up & Down in New York's West Village.

Rih is of course totally comfortable with showing off tons of flesh: in March, the "Stay" singer wore a see-through mesh dress that revealed her bare breasts and sexy bikini photos litter her now disabled Instagram page.

Celebs flocked to the stunner's shindig, from Beyonce and Jay Z to Kristen Stewart and Charlize Theron, who partied well into the wee hours of the morning.

Keep doing your thing, girl!



So much hotness on the Met Gala red carpet:
