I can't find Nick Robinson's address. Should I send my mail to his agency or his manager's address? Do you think he'll get the mail?

Ok so the real reason why I'm asking is because I want to send him fanmail and ask him to my senior prom. (I KNOW, VERY UNLIKELY but I'd at least like to ask him so that I can so I have no regrets). Please help me find his address, I need to get this out of my system.

I'd really like to send him some fan mail I can't seem to find his address anywhere.
