HOV gave 12 year old Justin a chance of a lifetime, to rap on stage during "The Magna Carter World Tour" show in front of a packed arena in Greensboro, NC.
He caught the attention of Jay by holding up a sign reading "CAN I RAP FOR YOU?"
Once brought on stage he performed Jay-Z's verse from "CLIQUE" acapella for the entire crowd to hear.
