Nicole Kidman shows off her model figure in a flowing blouse and mini skirt as she shares a cheeky tribute to husband Keith Urban

They have been married since 2006.

But Nicole Kidman proved the spark is alive and well with husband Keith Urban when she shared a tribute to him online last weekend.

The 59-year-old actress posted photos from an outdoor photoshoot to Instagram on Saturday, showing off her model figure in a flowing white blouse and miniskirt.

Nicole praised her husband in the caption, writing, “Nothing better than going home with U,” before tagging Keith and using the hashtag #GoHomeWU.

Her post referenced Keith’s new song Go home WU, the latest single from the country singer’s upcoming new album.

The footage showed an ethereal Nicole posing against a white wall outside her home in a storm, her hair blowing in the wind.

The leggy star completed her look with stockings, a gold chain and a pair of pointy pumps.

It comes after Keith admitted he was ‘scared and nervous’ about asking Nicole out after they met.

Keith made the admission Friday at the American Film Institute’s Life Achievement Award gala.

He admitted that he was initially nervous about asking her out because he thought she was a “real princess” when he first started pursuing her.

‘I tried to play it cool, but inside I felt like I had snuck into the royal ball simply because Nic had such an otherworldly appearance. “It felt a bit like meeting a real princess,” he told the crowd.

‘And despite that, I still managed to get her phone number on a small piece of paper. I was scared. I was nervous about calling her.”

“I, as you’ve probably figured out by now, worked up the courage to finally call her,” the country star recalled.
