The couple also recently attended the Swisse Celebrate Life Ball, an Australian fundraiser for two children's hospitals, according to Deseret News.

Kidman has been outspoken about her support for kids' charities, telling Australia's Herald Sun that she regularly goes to children's hospitals to help raise awareness and to interact with the children.

"It’s one of the most important things I do," she said. "I have been doing it since I became well known in the movie industry."
