The Hollywood star and cinematographer Danny are also the proud parents of 14-year-old son Henry. The couple work hard to give their children a private life out of the spotlight and have done an excellent job at doing so.

Julia previously recalled the moment her kids asked her about her job for the first time. "I don't think they will ever have a true sense of [my fame]" she told Harper's Bazaar in 2018.

The Hollywood couple are incredibly private

"I think I told you once when they were starting to figure it out, it was like, 'You're famous?' And I said, 'I think a lot of people might have seen the movie that I'm in or might know who I am.'"

They then went on to ask their mum: "Are you more famous than Taylor Swift?"
