The ‘Blue Jasmine’ actress has been married to theatre director Andrew Upton – with who she has sons Dashiell, 12, Roman, nine, and Ignatius, five – for 16 years but she doesn’t think sharing an industry with her spouse makes any difference to their union.
She said: “I don’t think it’s more difficult for actors to have a good marriage than anyone.
“I think in the end a really important component of any relationship is honesty – and it also comes back to luck.”
However, the Australian star admitted she feels “fortunate” to have such an “amazing” husband.
She told Britain’s HELLO! magazine: “I’m incredibly fortunate to have met the intelligent, generous, risk-taking, stimulating man to whom I am married. He’s really amazing.”
Cate says she lives in a happy household, and she never takes work home with her because her kids are “not interested”.
She said: “I don’t take my work home – my children are not interested in me bringing home the characters I play.
“My boys are great kids, hilariously funny. We laugh a lot when we’re at home.”
