सवाल about Fan-mail? Not urgent but I would like an answer as soon as possible :)

Okay so found what is supposedly Matthew Gray Gubler's mail address.

Matthew Gray Gubler
Brillstein-Grey Entertainment
9150 Wilshire Blvd.
Suite 350
Beverly Hills, CA 90212
USA

Now I'm willing to bet this is fake because lets face it, the internet cant always be trusted; but I kinda dont wanna miss out if it is real. Does anyone know if it is, and if not, what the real fan-mail adress is?
