Keith and Nicole have been married since 2006 and share daughters Sunday, 11, and Faith, nine. The celebrity couple have an incredibly strong relationship and the Big Little Lies actress recently opened up about their family unit and how they balance work with looking after their daughters. Talking to WSJ. Magazine, the mother-of-four said: "We have a system worked out to keep the family together. When Keith's not touring, it's much easier. He'll be on tour next year and then I just don't work as much. Literally – it will become imbalance and we will change it."
