Nicole Kidman and Keith Urban’s Sweetest Moments in Photos Through 18 Years

• Nicole Kidman just celebrated her 56th birthday, marking yet another milestone in the veteran actress' life.
• One of her biggest gifts is the enduring love she shares with her husband Keith Urban, whom she proudly calls her partner.
• Through the ups and downs, they've remained faithfully devoted to one another. Here's their life together in pictures.

The moment in 2005 when Nicole Kidman and Keith Urban's paths crossed for the first time, neither could have predicted they would end up sharing their lives together.

Even so, a picture taken shortly after being introduced to each other would forever mark the occasion, and their first of many pictures together.

At the time, Kidman realized she had a crush on Urban. The musician, however, didn't seem so interested in her.

After their initial introduction, it took Urban four months before she gave the actress a call. "I had such a crush on him, and he wasn't interested in me!" she hilariously admitted years later.

When the relationship finally got going, the pair realized they had a lot in common. Both had grown up in Australia but didn't know of each other until they were already in the US.

Early into their relationship, Kidman had a shining thought one morning, realizing that it was Urban she wanted to marry. They were standing outside her front porch, and she found herself hoping they'd one day be end game.

A year after they met, Urban and Kidman wed. It was the beginning of a new chapter for both of them, one that the country crooner likened to a new life. "Okay, life starts," he said, describing the beginning of their married life.

Admittedly, Kidman only got to know her husband when they were already married. She noted how spontaneous she was when she agreed to marry the musician.

As for the secret to their long-standing marriage, Kidman shared that it was knowing you needed to contribute to its success. They focus on what works for each other, and it benefits their marriage altogether.

However, through the years, they weren't spared from difficult challenges that tested their commitment to one another. One challenge they faced was Urban's struggles with alcoholism.

Kidman's unwavering support was crucial in the singer's quest for sobriety. He realized he needed help with his addiction, and he had a stint in rehab to become a better person for himself and for his family.

Kidman called for intervention with Urban's closest circle. Without question, he checked himself into rehab and stayed there until he was ready for a new life.

Another challenging thing to come to their family was the death of Kidman's father. At the time, she leaned on her husband for support, calling him her "rock." In another instance, she also lovingly mentioned Urban as her "partner."

The celebrity couple has two daughters together, Sunday Rose and Faith Margaret. They are doting parents to their two girls, raising them in Nashville and spending as much time as they can with them as possible.

In fact, whenever Urban can make it home from a gig early, he does just that. Regardless of whether or not he gets home at one in the morning, he's up the next day making breakfast for his girls.

The Urbans have been subject to divorce rumors for years. They choose not to deny them but instead, ignore them altogether. "Our life will be our way of defending it," the country star once said.
