Contacting Zac Efron?

Ok, so I apprieciate that some people don't like him but personally I love Zac! I really want to send him fan mail but I dont know what address to send it to... I have looked at wesites but they all seem to have different addresses on. I dont want to end up sending a letter to some pedo that gets my address and stalks me for the rest of my life lol. So if you have written to him or you know the CORRECT address, can you tell me pleasee? Thankyou x
