I have just received news from Sophia that she has changed her UK agent. Her new agent is Lindy King from United Agents, who has also worked with stars such as Keira Knightley, James McAvoy, Ricky Gervais and Alan Bennett.
Most importantly, a change of agent means a change of address. You can now send fanmail to Sophia via her agent at the following address:
c/o Lindy King
12-26 Lexington Street
