+ I heard she was with Knight Light Management.

So where do I write too?

I would go with the one listed on her website

I would go with the one listed on her website

sorry, which one is that? all these we're listed different places.

From what you posted, I'm guessing it's the one on Melrose Ave.

Third address you've posted is for sending fan mails to Shake It Up and SIU is serie on Disney Channel. When Bella worked there, fans could send her fan mails but it's not her official address for fan mails, it doesn't belong to her. Every address you've posted is right but you posted this in 2011 and Bella changed her PO box, so her official address is posted on her verified Facebook:

BELLA THORNE
C/O Persona PR
8840 Wilshire Blvd 2nd Floor
Beverly Hills, CA 90211
