Same Agent
Addison has the same agent as Liam Aiken, and she knows him in real life.
I actually wish I lived in the New York area because Ellen Gilbert (her talent agent) seems to get all her clients work.
Note: I'm assuming she knows Liam Aiken because she posts on his bands myspace, and lives close by. She's probably been to one of their concerts or something, but if not she may have not met him ^^
