Nicole Kidman marks 19th wedding anniversary with husband Keith Urban

Nicole Kidman is celebrating nearly two decades of marriage with Keith Urban.

The Big Little Lies star, 58, marked the special milestone with a black and white photo of the longtime couple backstage.

The actress could be seen smiling and resting her head over her husband's shoulder with her one arm draped around his other shoulder.

'Happy Anniversary Baby @KeithUrban,' she captioned the post with a red heart.

The singer-husband also dropped a red heart emoji in the comments within minutes.

The couple, who married in 2006, also share daughters Sunday Rose, 16, and Faith Margaret, 14.

Their wedding marked five years since her split from actor Tom Cruise, with whom she had adopted two children Isabella and Connor.

Urban once spilled the beans on their marriage secret in a 2022 talk show appearance.

"We're just a couple who work things out, go through things together, life, and support each other the best way we can and try and raise our family," Keith shared on Jessica Rowe's podcast series The Big Talk Show.

"Underneath it all, we're as normal as you can get I reckon," he claimed, before reflecting on how he initially thought the Hollywood actress seemed out of his league when they first met at the G'Day LA event in 2005.

"Four months into a marriage, and I'm in rehab for three months with no idea what was going to happen to us. Nic pushed through every negative voice - I'm sure even some of her own - and she chose love," the Somebody Like You hitmaker added.
