Justin Bieber

Boys will be boys. Teen singing sensation Justin Bieber almost got into a lot of trouble Thursday when he nailed a state trooper with a water balloon, soaking him from the belt down. The officer was ready to cuff the 'Baby' singer, but thankfully his bodyguard managed to talk him out of it, E! News reports. "Still laughing. GREAT DAY," Bieber tweeted after the show.
