In the music video for Enrique Iglesias' new single, "Tonight (I'm Fuckin' You)," he woos sexual conquests with, "Please excuse me, I don't mean to be rude, but tonight I'm fuckin' you." And he does. Lots! The NSFW video, inside.

Today marks the day that Willow Smith—aka the 9-year-old daughter of Will and Jada—releases her first music video, for her first single, "Whip My Hair." And, honestly? It's good. Actually, it's really good. Like, really good. Watch inside.

How does Bristol Palin get back at Levi Johnston for his steamy appearance in a music video? By making a cameo in one for an Alaskan rock band, apparently. She plays Mother Nature! And wears a fur coat! Watch inside.

Before their hair-raising, curse-strewn telephone calls were the talk of the tabloids, Oksana Grigorieva and Mel Gibson made a music video together. Mel directed Oksana dodging flying knives and writhing rhapsodically in a fire. In retrospect? Kinda creepy.
