Rihanna Has Perez Hilton on a Leash!

In Rihanna's just-released music video, "S&M," celebrity blogger Perez Hilton must have been a very bad boy -- he's tied up, and then he's on a leash!

In the tongue-in-cheek vid, Rihanna's love/hate relationship with the media has her singing, "Sticks and stones may break my bones, but chains and whips excite me."

Check out the naughty new video!
