Rihanna sports a machine gun as an accessory in her tough but stylish video for the new single off 'Rated R.' The R&B/pop diva, who's become quite a style maven in the last year, is fully embracing her 'Good Girl Gone Bad' image lately and describes the look for 'Hard' as "couture military."

"Everything is surrounded around the idea of something military," Rihanna explained to MTV. "We have tanks, we have troops, we've got helicopters, we've got explosions. We've got lots of cute outfits, lots of bullets. It's crazy."
