A great song and an even better music video with a powerful message about domestic violence. Rihanna, who was abused by ex-boyfriend Chris Brown in 2009, decided to collaborate on the song because "it was something that needed to be done."
The Joseph Kahn-directed (He also did Kylie's "All The Lovers") video stars Megan Fox and Dominic Monaghan. Fox generously donated her paycheck for the shoot to a women's abuse shelter.
Watch the video AFTER THE JUMP.
