Remember - once you've watched this video, it'll be there in your brain forever. There is no going back.

Truth is, you may disapprove - or worse. And it certainly shouldn't be seen by Rihanna's millions of tweeny fans - and many of them will watch it (and already have). Yes, that's bad. However, this is also a mouthwatering first collaboration between a great pop superstar and one of the most creative music video directing outfits around. Sometimes these things don't work out. In this case, it absolutely delivers. 

This is big and bad and top-notch entertainment - rated R. Megaforce have simultaneously managed to make Rihanna nastier and sexier than ever, but also smarter and funnier. It's turned out to be a match made in heaven - or somewhere way more interesting.

Lets face it, this is why music videos were invented in the first place.
