Love is in the air for Keith Urban and Nicole Kidman. The 50-year-old country music singer wowed his Chicago fans on Saturday night after surprising them by welcoming his wife on stage.

On Aug. 18, Saturday, Keith Urban serenade countless fans during his concert at the Hollywood Casino Amphitheatre. After performing a few songs from his latest album "Graffiti U," he welcomed two fans onstage, one of which was pregnant and carried a sign that reads: "Baby's first time onstage."

After introducing the two fans, Keith Urban all of a sudden shouted to his wife and urged her to join them. Nicole Kidman, then, walked out on stage and kissed her husband on the lips and warmly embraced the two fans, before the singer continued the remainder of his show for the night.

This only dismissed rumors that Keith Urban and Nicole Kidman's marriage is in trouble. In 2017, Star Magazine (via Gossip Cop) reported that the latter is considering divorce due to her husband's infidelity.

The report also includes a series of photos showing the "Meet Me in St. Louis, Louis" hitmaker and television personality, Alecia Davis, exchanging a romantic hug at the 2017 California Mid-State Fair in Paso Robles.

"I'm sure Nicole Kidman will blow a fuse when she sees the pictures," an unnamed insider was quoted by Star Magazine as saying. "There have been whispers about trouble between them for a while, and even speculation about a divorce. Given what she's had to deal with, I just don't know how much more Nicole Kidman can take," the insider added.

Adding fuel to the fire, National Enquirer reported that the "Big Little Lies" star is getting close with "Top of the Lake" director Garth Davis to get back at her husband for the alleged cheating.

However, the 51-year-old actress and producer had no reason to get revenge, as her husband never did anything wrong in the first place. The couple also opts not to care those endless rumors anymore.

Instead, both of them have their hands full with several projects. The "Bush Christmas" star will star next as Nancy Eamons in Joel Edgerton's upcoming coming-of-age drama film, "Boy Erased," as per Variety. Keith Urban, on the other hand, is currently hitting the road on his "Graffiti U World Tour."
