There are two reasons actress Nicole Kidman remembers the day she married country star Keith Urban.

Why Keith Urban Isn't Jealous Of Wife's Date With Late Night Star 

The first is that she was marrying the man she loved and the one who would go on to father her two young children. The second was, naturally, the dress.

On Thursday the Paddington star talked with E! about her different looks over the years, but she admitted that her absolute favorite will always be that wedding dress.

"It's the most exquisite dress and it is so beautiful," the actress said of the high-waisted lace dress with intricate sleeves and elegant edges. "Nicolas [Ghesquiere] made it for me and it is wrapped in special paper and will be passed on to whichever daughter wants to wear it."

Despite their busy schedules, Kidman and Urban can't get enough of each other when they appear in public. On New Year's Eve the two locked lips for a passionate midnight kiss onstage at Niagara Falls. On Jan. 10 the stars laughed and goofed around as they walked arm-in-arm down the red carpet at Kidman's Paddington premiere in Los Angeles, Calif.

When it comes down to it, the singer and the actress are all about family. "I don't want to miss any of it," noted Urban during an interview with CMT in December. "None of it. I don't want to miss any time with Nic and our family."

Kidman and Urban currently live in Nashville with their two young daughters, Sunday Rose and Faith Margaret.
