There doesn't seem to be a day that goes by that we don't see a bikini-clad Rihanna livin' it up poolside -- or in this case, on a private yacht. The sexy singer recently stripped down to a bright blue bikini to catch some sun and do a little dancing in Saint Tropez and X17online.com was there to document the action.

The pop star drank the day away -- she and her pals were sipping on Champagne from some very fancy crystal glasses -- and even got their dance on.
