Can Emma Watson be privately contacted?

Answer 1

I'm quite sure she can be, but that information will most definitely be kept private, or when made public it will be immediately changed and only a few people notified.

Don't try to harass the poor girl.

If you want to send a letter to her, try finding her talent agency and write it c/o to them, including a SASE. Don't expect a reply, but say a wish as you stick it in the mailbox .
