Following in the footsteps of shining examples Whitney and Bobby, Rihanna and Chris Brown (what is it with singers with the last name of brown?) are this week's Hollywood HOs winners. Apparently, getting your face bashed in inspires you to hook up and work with the basher. Not only are they supposedly back together on the sly (his current girlfriend is Karrueche Tran), but they have collaborated on a new song, "Birthday Cake (Remix)". It's a charming little ditty with lyrics that would embarrass a sailor on shore leave. I will not quote them, but you can find them here. If you have forgotten what the gentleman caller did to his lovely lady, the pictures below can remind you.
