Rihanna gets tied up and dragged around in this video. Celebrity blogger Perez Hilton makes a cameo in the video, led by Ri-Ri on a leash like a dog. The video was directed by Melina Matsoukas, who has done many of Rihanna's music videos.
"S&M" is already gaining a lot of views on her Vevo on youtube.
What do you think of the video?
