Keith Urban is feeling the love!

The country singer turned 55 last week and his wife Nicole Kidman made sure to honour the occasion.

Taking to Instagram, the 55-year-old Moulin Rouge star shared a never-before-seen picture of herself and Urban to mark the special day.

In the snap, Kidman can be seen wearing a black sequin off-the-shoulder mini dress as she and Urban share a little smooch.

Alongside the photo, the Australian actress wrote: "Happy Birthday my love ❤️❤️❤️❤️ 4ever."

Urban and Kidman have never been the couple to shy away from public displays of affection.

It was a fast romance for the singer and the actress, who met in January 2005 and began dating six months later.
