The pop star took the theme of her hit track 'Diamonds' to heart as she continued her Carnival celebrations at the Crop Over Festival in her hometown in this rather revealing two-piece that showcased her Isis ribcage tattoo... and plenty of flesh.
Never one to shy away from the camera, 25-year-old Rihanna uploaded several shots of herself in her costume throughout the day as she enjoyed the sunshine – and drinks! – on offer.
One particularly revealing shot gave us a good look at Ri's, um, backside, as she sashayed along a corridor. Another equally racy pic gave a close-up look at Rihanna's intricate and barely there bikini top... among other things.
One thing is for certain: there's no denying she isn't afraid to flash the flash and she certainly knows how to stand out from the crowd. And have fun.
What do you reckon? If you've got it flaunt it? Or is this just too much? Let us know below.
'We Found Love' singer Rihanna is back in her native Barbados while she enjoys a break from her gruelling 'Diamonds' world tour that ended its European leg last month.
She visited the UK and Ireland earlier in the year and has played the festival circuit with appearances at T In The Park and a surprise cameo at Wireless.
Ri kicked off the mammoth jaunt - in support of latest album Unapologetic - in March, and has been going pretty much non-stop since then. She'll resume the tour next month with schedule dates including China, Australia and the US.
Judging from these pictures, however, it doesn't appear she's using her downtime for some R&R!
