How can i get a direct question to John Cena?

I have a two sons age 9 and 4 and they are huge fans of his. But my 4 year old is over the top for him. He goes to bed watching him and wake up asking questions about him. He knows all of his moves and songs by heart and have no problem doing a demo. Soon WWE will be in Richmond Va and I plan to get them tickets. Is there anyway possible that he could meet him? It would be the story of his life.
