Facebook/Rihanna

Anyone else get the feeling Rihanna's a bit of an exhibitionist? Singing and 'acting' aside she could make a very good career out of flashing her bits on the internet.

One week it's see-through tops in New York and the next she's half naked on a tread mill. So what's today's titillating treat from our favourite Barbadian? It's RiRi in a bikini, oiling herself up with half a nipple hanging out.

The nipple slip pic's are part of a series of shots taken on a recent holiday and with the shame only a porn star could possess she's popped them up on Facebook for us all to see.

Perhaps she should consider just getting it over and done with and stripping off for Playboy or maybe she could follow in the footsteps of Laurence Fishburne's daughter.
