Rihanna is raising temperatures in the Italian resort of Portofino in what might be her tiniest bikini yet.
The star has been sailing arounnd the Mediterranean with her pals, and was pictured having fun during a snorkelling session.
Rihanna's had a busy year, so it makes sense that she's been letting off steam. Despite complaints that the boat based partying might be getting out of hand, she still seems to be going strong.
Meanwhile Rihanna's infamous ex Chris Brown has reportedly been partying with Paris Hilton in Vegas. Paris is said to be drawn to his "bad boy" rep - even though there are rumours that Chris hooked up with Rihanna when her yacht was docked in St Tropez.
