First, let's be honest, that may not actually be a K-9. It might just be the world's most clever little person in a dog suit discovering a way to get Rachel Bilson to hump his backside. I'm not exactly sure what was going down on the streets of L.A. between vastly underrated hottie Rachel Bilson and the furry beast that was walking her, but I know that I'm hardly the man to judge others on their furry play conduct. Live and let live and, please, somebody get pictures of Rachel bathing that thing. Enjoy.
