Keith and Nicole sing for the kids

Keith Urban wasn’t the only one serenading staff and patients at Australia’s Monash Children’s Hospital last Friday,  wife Nicole Kidman  joined in on the impromptu concert. Down under for a fundraising event benefiting the Celebrate Life Foundation, the couple stopped by the facility to share smiles and lift a few spirits. And it’s not the first time; Kidman is somewhat of a regular. When Urban suddenly grabbed a nearby guitar and launched into “Amazing Grace,  Kidman was among those to jump right in.
