Rihanna Exposes Her Booty In A Carnival (PHOTOS)

 As a renowned party rocker, she doesn't need many excuses to let her hair down to excess.

So Rihanna took to the Barbados carnival scene with aplomb, partying through to the early hours of Saturday morning in the island's capital Bridgetown.

And the 25-year-old singer looked typically striking
in a nearly sheer white monokini, decorated with sparkling metallic panels.

Green face paint, blue and silver sunglasses, practical baseball boots and a white veil over her new short curly hairdo completed the look.

The star clutched a drink in one hand as she grinded behind several other partygoers at The Foreday Morning Jam party.

At one point, she also showed off the backless detail of her ensemble, getting down on all fours for some kind of breakdance move.
