Will my true love end up getting my letter?

Okay, so I checked out this celebrity directory book from the library, and in it my true love's address is listed. The thing is, the book was a 2006-2007 edition, and this guy has moved since then. I know that the old address is the correct address of where he used to live, so do you think that if I sent a letter there, it would be re-directed to his new address? (whatever that is)
