While in concert in Greensboro, N.C., Sunday night Jay-Z invited a young man onto the stage to perform with him. The 12-year-old boy seized the moment and killed it!!!

Justin's mom says that a previous concert he was overlooked, and that is why they decided to attend another Jay-Z concert. Luckily, this time it was Justin's turn and he owned it.

Justin's mom tells TMZ that they went backstage after the concert, but no numbers were exchanged, and Jay-Z did not make any promises to the kid. Still, what a moment it must have been for this young man.
