Yes he does! He even came out with a voice over for the song "Speaking In Tungs" by Cam'ron. Look it up on Youtube. Justin likes to come up with silly alter-egos and one of them is Shawty Mane, which is when he likes to think he's a rapper. He also rapped the Ludacris part of his song "Baby" and did it perfectly!
