Why do A-list ladies keep giving this guy a shot? The singer has committed practically every cardinal sin in the relationship handbook. Most damningly, he frequently blabs about his partners to the tabloids, calling Jessica Simpson "sexual napalm" years after they split, and he even held a press conference with the paparazzi back in 2009 when he broke up with Jennifer Aniston. (Ouch!) So girls, if he tells you he loves you, there's probably a reporter nearby.
