As everybody has said, some do, some don't. I have a friend who writes to her favorite celebs asking for autographs as she collects autographs. She has been very successful and has people like rihanna, taylor swift, the whole skins cast... and soooo many more send back autographed pictures. I know that some movie starts reply on twitter about their movies because I have stalked a few celebrities myself. Lol. As Irene said, you have to verify that it's actually them because there are so many fakes around these days.
Celebs are pretty much like the rest of us. And if you think about it in their shoes, they only got there because of their fans so I think all of them do. But also know that they have a gazillion fan emails and may not get to all of them, and of course some are different than others.
Ive had a lot of celebs follow me on twitter & actually talk.
Just make sure its a verified account.
Yes some do. I know that for example Justin Bieber replies to his fans and I've had other celebs reply to me
i know about these things
