Cate Blanchett has revealed that the recipe for a happy marriage is to share an email address.

The 'Blue Jasmine' star said that she runs her household as a ''well-oiled machine'' by reading all messages addressed to her husband, Andrew Upton, the Sydney Morning Herald reported.

She said that Upton is happy with the arrangement because he hates emails and as they share an account, she is left with the correspondence.

Blanchett added that they work together and it's a way of synchronizing their lives and she can see what he is up to.
