Justin Bieber is a busy man, but he still makes time for his friends. So when Sean Kingston was left in critical condition after a water skiing accident in 2011, the Biebs made sure to see his pal and collaborative partner. "That's my lil bro, man," Sean later told MTV. "I see that he's a loyal friend. For me to be in a life-or-death situation like that and then for me to come out the hospital and know that he's calling my mom, calling my manager, calling everybody asking how I'm doing, I see that he's a great friend -- a great, true person at heart."
