They're celebrating their milestone 10th anniversary together later this year, and Keith Urban is dishing on what keeps his marriage to Nicole Kidman so happy and healthy after all that time.

The singer and American Idol judge opened up to Entertainment Tonight about his marriage and revealed that he's ecstatic to be hitting this particular milestone, which he admits seems like a rarity for most couple these days.

"Ten years is fantastic!" he said. "It's like 30 in this day and age."

He also dished on what helps keep their marriage so fresh and wonderful after such a long time--admitting that his best tool has been consistently trying to woo her over and over again.

"Dating. Keep dating your wife--that's it," he said. "I'm still trying to get her to go out with me."

However, though he's excited about the anniversary, he hasn't planned out what he'll do for his wife yet to celebrate.

"I'm working on that," he said. "Give me a minute, we've got 'til June."

Last year, the couple spent their wedding anniversary together at a stop on Urban's tour in Michigan, where fans in the audience held up signs wishing the couple a good day.

The two then took to social media to directly address the fans and thank them for the love and support.
