Akon isn't really a stranger to controversy. He spent three years in prison for auto-theft and came under criticism from practically everyone for simulating sex onstage with an underage girl. But perhaps his most famous misdemeanour occurred in 2007, when an audience member threw an object at him. At Akon's command, stage-hands forced the thrower onto the stage. The well-built singer grabbed him and aggressively launched him back into the audience. The kid was only 15, and he landed on (and caused concussion to) a young girl. The whole thing was caught on camera, and Akon was charged with endangering the welfare of a minor and second-degree harassment, for which he was sentenced to community service.
