Here's the previously-leaked clip for Rihanna's new David Guetta-produced, Doritos-endorsed single "Who's That Chick." The Jonas Akerlund-directed clip sports double the Rihanna; one that smiles a lot and dresses in Katy Perry colors and another one that grimaces and cries black stuff like Dania Ramirez's character in Heroes. That's mainstream edginess at the bottom of 2010.
