Ok Perrie has one and its the same as one direction but otherwise no one else has one

well considering Danielle is a professional dancer, it would be appropriate to send to her & same for Perrie, she's in a band.
Danielle has a website.. try that

yeahhh...I don't think it's really appropriate to be sending fan letters to the girlfriends of a band...

I mean they didn't choose by any means to have themselves thrusted in the public light....try putting yourself in their shoes? you can't help who you love...

if you do send something to them...all the luck to you, but maybe think twice? (i'm by no means here to tell you what to do! just my suggestion!)

Hi! I don't believe thy have an address as of now, as they aren't exactly 'famous'. They are just known to be girlfriends of One Direction's members. Maybe you can try asking them via Twitter?
I love One Direction, by the way!
Oh! But one thing. They may not have a fan mail address, as they are afraid of crazy fans sending them DEATH THREATS via there, so be warned.

I was wondering if anybody has an address for Perrie Edwards/The Little Mix, Danielle Peazer or Eleanor Calder?
Thanks!!!!
