RihannaRihanna has premiered a graphic and controversial new music video for her latest single 'Man Down,' in which she takes revenge on a sex offender by shooting him.

Rihanna, who was infamously assaulted in 2009 by then-boyfriend Chris Brown, literally shoots a man down at the opening of her Anthony Mandler-directed, Jamaican-filmed video.

The 'Hard' singer opens fire on a man at a railway station before a series of flashback images reveal that the murdered man was Rihanna's nightclub assailant.

Rihanna took to her Twitter page to tell fans "Thank you for the amazing response on Man Down video I love you guys, and I love that u got it!!! Young girls/women all over the world... we are a lot of things! We're strong innocent fun flirtatious vulnerable, and sometimes our innocence can cause us to be naive!"
