Nicole Kidman is lending her Balenciaga gown from her wedding to country star Keith Urban to a new exhibit in Australia — from which she and her husband both hail — at the Powerhouse Museum.

The exhibit runs through 2018 and will feature more than 60 wedding gowns dating back as far as 1822. It will be a tribute to love, which Kidman says is the reason she was more than happy to do it.

“I’ll support anything that supports love. Truly. Isn’t it the essence of everything? It can heal so many things,” she told InStyle Magazine (quote via Hollywood.com). Titled Love Is … Australian Wedding Fashion, the exhibit will display dresses from a number of famous Australians throughout the decades, from the 1920s, to the 1960s and modern day.

Kidman and Urban tied the knot in 2006 in Manly, Australia, which is outside of Sydney at Cardinal Cerretti Memorial Chapel. They recently celebrated their tenth wedding anniversary, but Urban is still pursuing his wife romantically after all these years.

“Keep dating your wife — that’s it,” he encourages, adding that he can’t slip on his game if he wants her to say yes to dinner. “I’m still trying to get her to go out with me.”

Kidman played a significant role in Urban’s sobriety journey, he says, crediting their marriage with giving him the motivation to do it. “I caused the implosion of my fresh marriage,” he recalls. “It survived, but it’s a miracle it did. I was spiritually awoken with her. I use the expression ‘I was born into her,’ and that’s how I feel. And for the first time in my life, I could shake off the shackles of addiction.”

The Aussies have two daughters together, Sunday and Faith.
