Re the name "Shawty Mane", Justin said this: ""Shawty Mane, I don't know, me and my friends were just messing around and they were like 'Shawty Mane' and I was like 'Yeah, that'll be my nickname"..."
"Shawty Mane is just like a funny character," explains Bieber. "You know Justin Bieber is not a rapper, and it would just be lame if I came out rapping. It's lame anyway because I'm like a pop singer, but I thought it was funny, I just did it as a joke. It wasn't like anything serious"...
"I thought it was fun, I like rapping," said the teen pop star with a smile. "Maybe in the future, Shawty Mane will come back" (http://www.justinbieberfans.org/justin- ... come-back/).
I don't want to belabour this. He's just a child.
