I've never seen any successes from Bridgit. I've wanted to write to her for a long time. I do have a request out still for Debby Ryan via her agency, and even have a sticky note on my desk that's been their for months that reminds me to contact you if I hear from her.

I wrote to Debby Ryan at that address & got her REAL autograph in the mail about 2 weeks later!!!

I have not tried Bridgit Mendler's address yet though. Hope this helps

I found this address that said you could request an autograph to Emma Watson there, but it's in California so I don't know if it'll work since she lives in the UK.

Emma Watson
Special Artists Agency Inc
(Talent Agency)
9465 Wilshire Blvd
Suite 470
Beverly Hills, CA 90210

I also found these addresses for Debby Ryan and Bridgit Mendler:

Debby Ryan
c/o The Disney Channel
3800 W Almeda Ave
Burbank, CA 91505

Bridgit Mendler
c/o Elaine Lively LA Entertainment
1317 N San Fernando Blvd #155
Burbank, CA 91504

Has anyone ever gotten a success from any of these 3 addresses?
