Rihanna Accidentally Flashes Butt While Walking into A$AP Rocky’s Fashion Show

Rihanna went to support A$AP Rocky‘s fashion pursuits … but her outfit gained the most attention when she accidentally flashed her backside.

The singer-songwriter stepped out in an all-black ensemble Friday night to attend her man’s AWGE fashion show in New York City … and her leather jacket opened a bit too wide and revealed the star’s famous derrière.

Check it out … the jacket’s skirt is split in the back and the split reaches just a bit too high up her legs, revealing the bottom of her bottom.

RiRi quickly readjusted the jacket … stopping the crack from showing any of hers.

Despite the fashion faux pas, Rihanna looked chic as always … just like she did recently at Paris Fashion Week, where she flashed her cleavage and even during a recent trip to the grocery store.
