Keith Urban has shared a photo online showing the moment he and wife Nicole Kidman first met.

The country music star uploaded the sweet image to Instagram to mark his 10th wedding anniversary.

The snap shows Keith and Nicole together, a few minutes after they met for the first time at the G’Day LA gala in 2005.

He wrote: “Our very first photo together 2005, minutes after being introduced to each other.”

The couple went on to tie the knot in 2006 and have two daughters together – Sunday, seven, and Faith Margaret, five.

Keith later spoke about his anniversary as he performed in Boston.

He told the excited crowd that he was planning to jet Down Under after the show to celebrate his anniversary with Nicole, who is currently shooting in Australia.

The singer uploaded a photo from the show and wrote: “It was an extra special night because it was our 10 year anniversary and you guys made the sweetest signs down in the front. It was amazing, thank you so much!!! – KU #ripCORDWorldTour.”
