Bottoms up!

Rihanna flashes her bum in tiny bikini in more sexy pictures from her holiday

The Umbrella singer seemed relaxed as she posed for seriously sexy shots

BODY-CONFIDENT beauty Rihanna swigged on a bottle of booze as she flashed her bum AND boobs in yet another racy bikini.

The pop babe was more than happy to pose for a host of swimwear selfies in a very sexy two-piece with grey knickers and a zesty multicoloured top.

The Umbrella singer's shapely booty was on full show as she stood on a set of steps while necking back the beer.

The alcoholic treat seemed to be RiRi's holiday accessory of choice as she headed into the crystal clear waters.

With the triangle-top swimwear boosting her cleavage, the star seemed keen to draw even more attention to her chest.

Getting her model-like vibe in full swing, the chart-topper clutched the bottle close to her boobs as she gazed into the waves.

She oozed beach babe style with her wet hair slicked back and the waters crashing against her body.

She then plonked the drink on her tummy as she stretched backwards to stare into the lens - with her chest in full view.

The cheeky pop babe then crawled through the shallow waters with her bum left deliberately sticking out of the water.

When she emerged out of the sea Rihanna, 28, wrapped up in a grey tie cardigan - though made sure her cleavage still commanded much of the attention.

As she became tired of hogging the limelight, she was joined by her photographer pal Melissa Forde.

The sexy pair sat on the deck of a swish boat and took to Instagram to film a snippet of their antics.

While Melissa sported a beaming smile, Ri Ri fooled around opening her eyes wide, pouting and snarling.

Melissa captioned the scenes: "#boats and hoes."

The pair grew up in Barbados together and are often snapped out with each other.
