Keith Urban and Nicole Kidman's adorable wedding anniversary post

Nicole Kidman and Keith Urban are celebrating 13 years of wedded bliss — and letting the world know they’re still very much in love.

Country crooner Keith shared an adorable Instagram snap with his Big Little Lies star wife, complete with a gushing caption to match their laid back demeanour.

"Thirteen years of magic , music, romance, wild adventures, and the ongoing discovery of pure love," he wrote. "Happy Anniversary Babygirl. xxxx - KU."

All loved-up

In the snap, Nicole, 52, in seen wrapped in her 51-year-old husband’s arms as they both laugh and appear relaxed on a beach.

Keith’s upper-arm tattoo spelling out his wife’s name is also visible - one of two he has in dedication to Nicole.

The pair’s martial bliss comes more than a decade after their high profile Sydney wedding, just 18 months after they met at the G’day USA event in early 2005.

Nicole gave birth to their first child Sunday Rose, in 2008, before the couple welcomed a second daughter, Faith Margaret, via surrogate two years later.

For fans of the couple, the latest very public display of affection comes as no surprise as both have a long reputation for telling the world of their loved-up status.

‘A lucky woman’

Last year, Nicole shared a snippet of their wedding video to celebrate her anniversary to Keith.

"Remembering 12 years ago today at a church in Manly, Australia," she captioned the video. "Still feels like it was yesterday. I’m a lucky woman.”

Similarly, Keith has made his devotion public through song with his hit ‘Maniac in bed’ reportedly penned about his longtime love.
