It might have been more of a shock if she'd decided to keep her clothes on.
But with a body like hers, pop star Rihanna can hardly be blamed for stripping off at every opportunity.
And what better place to show off her curves than the front cover of upmarket U.S. men's magazine GQ?
'I like to feel like a woman,' she said.'I have to be in control in every other aspect of my life, so I feel like in a relationship, I wanted to be able to take a step back and have somebody else take the lead.'I could absolutely be dominant, but in general, I'd rather... How do I say this in, like, a non-X rated version?'
For now Rihanna is single, following the end of her reported rekindled romance with Chris Brown.
