The 43-year-old, who has two sons, Roman and Ignatius, with husband Andrew Upton, said she has been taking the kids to work so that she gets to spend time with them, reported Contactmusic.
"We do what we love - it's not like we are running a supermarket or something. There is not a lot of separation between work and home life. The kids hang out at the theatre, and it all gets a bit muddled-up, but it somehow works," she said.
