Lil Za -- Justin Bieber's Still My Homie, But Boxing Saved Me (VIDEO)
Lil Za Bieber's Still My Homie ... But Boxing Saved My Life
Justin Bieber's BFF Lil Za had a better chance of fighting a jail cellmate than taking on an opponent in a boxing ring -- but the guy's turned his life around, and now he's throwing KO punches.
Za got pretty famous for getting in a ton of trouble with Bieber over the last couple of years -- he was busted for drugs during the infamous egging raid in Calabasas. The 21-year-old tells us, "When all that madness was going on, I decided to grab a hold of myself and do something positive."
Za's been training hard for the last year, and as you can tell from the video ... kid's got some skills. He came on TMZ Live to tell us about making the big change.
