Justin Bieber doesn't really know what to do about his ladyfriend. She's being pretty hot and cold; he can tell she's not being honest in what she's saying, and she's giving him a pile of mixed signals. So he's laying it all out on the table, over a throbbing beat and some plinking high notes that kind of sound like he's singing in a club in the middle of the rainforest. My question is, since when is my ex-girlfriend dating the Biebs?
