On Thursday, Urban and Kidman were snapped at Chatswood Chase dishing on KFC.
The couple kept a low profile as they squeezed in some late night browsing at the lower north shore.
“Just Spotted — Nicole Kidman and Keith Urban and kids shopping for kids clothes in K Mart Chatswood,” a lucky onlooker shared on Facebook.
The person also shared, "They did a big shop in Kmart. The staff were beside themselves taking photos! They didn't have to line up, they got a special cashier."
During the ARIAs the iconic Aussie couple delivered on maximum amounts of PDA.
The 51-year-old country superstar made sure his wife felt the love as he kicked off the show.
"Hi everyone, hi Australia," Urban said before focusing on Kidman.
"Hi baby, right in the front row -- hi!"
