Nicole Kidman and Keith Urban With Sunday and Faith Pictures

The whole Kidman-Urban family stepped out in Sydney yesterday. Nicole carried 1-year-old Faith while Keith held onto Sunday's hand. The foursome recently traveled Down Under, where Keith will appear on the Australian version of The Voice. He'll mentor a group of singers along with other coaches Seal, Joel Madden, and Delta Goodrem in the series, which will air sometime this year. Keith's been the one singing lately, since he hit the stage at the Grand Ole Opry for his first post-throat surgery show earlier this month and had two concerts in Texas over the weekend. He's not the only star to recently recover from the vocal cord procedure since Adele made her own return performance at last night's Grammys.
