Sure what else would Rihanna do while in a bikini only post some pictures to her Instagram account?
The singer was lounging around poolside and boredom/self-confidence must have kicked in and she decided to post quite a few pictures from herself soaking up the rays.
Not that we are complaining mind.

She also posted this picture which showed her, along with a friend, quenching her thirst below water.
JOE would like to point out that you should never, ever, drink and dive, but this was most likely for the benefit of the camera.
