The severity of what happened is in dispute, but fans and friends of Lil Wayne are banding together after the rapper's medical scare on Friday.
Usher, who made a surprise appearance during indie rock group the Afghan Whigs' concert at SXSW, asked the crowd to keep Weezy in their thoughts.
"I don't mean to bring everybody down, but right now I think I want to just ask something of you guys," the R&B singer began at the Austin, Tex., event.
"One of my fellow artists, good friend, Lil Wayne is going through a real hard time right now, y'all. And I just want to send a lot of positive attitude about his state."
