The actress and her country-singing husband, Keith Urban, recently toured the Melbourne Children's Hospital while they were in town for the Swisse Celebrate Life Ball. There was a guitar on hand, and Keith Urban gave an impromptu performance. Kidman joined her husband and the hospital staff in a rendition of "Amazing Grace."
"It's deeply sad," Kidman told the Herald Sun. "But, events like the Swisse Celebrate Life Ball ensure that we are able to give to families in need. Even if it is just listening and hugging and showing support, then it's worth it."
You can check out a video of the performance below. Kidman seems to hesitate at first, but she eventually gets into the groove. A loving glance from Keith Urban will do that to ya. (E!)
