Fisher and Cohen met at a party in Sydney, Australia in 2002, and became engaged in 2004. Prior to getting married, Fisher confirted to Judaism, and told The London Standard, "I will definitely have a Jewish wedding just to be with Sacha. I would do anything — move into any religion — to be united in marriage with him. We have a future together, and religion comes second to love as far as we are concerned."

On March 15, 2010, following Fisher's conversion, she and Cohen got married in Paris, France.

The couple has two children together, daughters Oliva and Elula. Fisher and Cohen welcomed their eldest daughter in Oct. 2007, and their second daughter in Aug. 2010.
