Rihanna's definitely not shy when it comes to showing off her rocking bikini body! Just a few days after the "Diamonds" singer posed in a snakeskin barely-there bikini, the 25-year-old again shared sexy selfies via Instagram on Aug. 9. 

Wearing a black sequined bikini, Ri Ri showed off her toned body and flat stomach, captioning the picture, "#Barbados," where she's currently vacationing. In another snapshot, she sits poolside, wearing the same bikini, paired with gold necklaces and a gold belly chain. 

Her vacation has been indeed a reason for various bikini photoshoots, as she's shared pictures of her incredible bod in recent days, including a picture of her sandy butt. "My beach is betta!" she wrote.
