The actress joined the country music superstar on stage in Las Vegas for the sweetest reason.
Urban took to Instagram to share a clip of the moment on Sunday, May 29.
The video shows the singer kissing Kidman after she walks onstage in the middle of his performance at the Colosseum in Caesars Palace.
“I want to get your jacket,” the “Moulin Rouge” star explains. “You put it on the floor and I’m worried.”
Urban tells the audience, “She literally said, ‘Don’t lose that jacket. And I’m like, ‘How am I gonna lose the jacket?'”
It turns out that Kidman was right, and the jacket had indeed disappeared.
“See! Look! You jinxed it,” joked Urban.
Thankfully, the sparkling black blazer was found after a brief search.
“Just a Saturday night in Las Vegas,” Urban wrote in his caption.
