Why He Doesn't Care:  13-year-old Lil Mouse caused quite a controversy when his video for “Get Smoked” came out in July. On Lil Wayne’s Dedication 4, he remixed the track, which gave Lil Mouse some major attention. The co-sign from Wayne brought up issues about whether it was right for him to promote the young rapper’s brutal lyrics about gangs, guns, and violence. Given that he got his start rapping about similar topics at a similar age, he's likely not concerned.
