Hot Or Not: Rihanna unveils artwork for new single 'What Now'...

For her official artwork for latest single 'What Now', Rihanna rocks a fitted black dress with sheer detailing, dark smokey eye make-up and a mullet hairstyle.  

With such a smouldering expression, Ri looks cold but sexy at the same time. 

The sensitive ballad, produced by Parker Ighile, serves as the fifth single off her #1 album 'Unapologetic'. A video for the song was shot in Thailand, but a premiere date has yet to be announced. 

What do you think of the cover art?
