In another heartfelt moment, while backstage, Keith removed himself from his guitar strap before placing it on Nicole's shoulders.
The Australia star was ready for her rockstar moment, posing with the instrument like a professional.
This, of course, isn't the first time the 55-year-old has joined the Wild Hearts singer on stage.
In May this year, Nicole was by her husband's side during a performance in Las Vegas.
As she joined the 54-year-old on stage, the actress beamed while embracing Keith for an affectionate hug. Meanwhile, the rockstar kissed Nicole gently on the cheek.
"What's your name; where are you from?" Keith singer jokingly asked his wife.
The Bombshell actress didn't hesitate as she replied: "Nicole Urban."
While the PDA moment brought many cheers from the adoring crowd, it didn't take long for Nicole to reveal her true motives for joining her husband on stage.
"I want to get your jacket," she told him. "You put it on the floor and I'm worried."
As Keith and Nicole went in search of the jacket hand-in-hand, the country singer told the crowd: "She literally said: 'don't lose that jacket'. I'm like: 'how am I going to lose the jacket?'," before admitting he couldn't find it.

"It's gone; you see, you jinxed it," the 54-year-old joked to Nicole, before the jacket was found with his guitar technician.
Once it was located, Nicole promptly donned the black blazer and bid farewell to the crowd.
"Just a Saturday night in Las Vegas," Keith told the audience following her exit.
