Rihanna flaunts butt cleavage in very low slung dress at Met Gala afterparty.

 I'm sure she thinks we're all already uninterested in seeing her titties and wants to provide us another thing to talk about. The singer wore this suprisingly low slung gold dress that showed her butt cleavage to last night's Met Gala after-party. No bra, no pata. Rihanna, dia iz God oooo. See more photos after the break.
