If Keith Urban and Nicole Kidman don't give you the ultimate relationship goals, no one can.

The couple celebrates their 10th wedding anniversary today and in honor of the milestone, we're looking back at some of their gushiest interviews and best marriage advice.

Read on for more on how Keith and Nicole are keeping their relationship stronger than ever after a decade together, and the 10 reasons they are our favorite celebrity couple of all time!

1. Their whirlwind romance.

Talk about a quick courtship! Nicole and Keith tied the knot after only one month of dating. But, hey, when you know, you know.

"I'm spontaneous. I jump in," Nicole told ELLE magazine in 2014, eight years into their marriage. "I kind of like getting married and then getting to know each other; I know that it sounds incredibly strange, but to me, it's a more natural process."

2. 'OK, life starts.'

Keith and Nicole were 38 and 39 years old, respectively, when they married. But to hear Keith tell it, nothing before that "I do" really mattered much.

"Meeting her and getting married," he told CBS Sunday Morning, "wasn't life-changing, it was life-beginning. It was literally, like, 'OK, life starts.'"

3. They're 'Fighters.'

Keith has been open about writing his Carrie Underwood duet, 'The Fighter,' about the beginning of his relationship with Nicole. So imagine our delight when the stunning actress adorably declared, "Oh my God, I love this song!" in a self-shot Facebook video. The couple gazed into each other's eyes and playfully lip synced the words to each other in the cute clip.

4. You're blushing, Keith!

Nicole couldn't help but gush over her husband's musical talents in an interview at the Academy of Country Music Awards, telling ET: "I've seen all the work he puts into it and the love. He's a musician, so every little tiny detail is all him, and I love that. I love that he's passionate about his music."

Modest Keith simply beamed at the compliment. See below!

5. All the PDA!

The couple remains fiercely protective over the privacy of their young daughters, but they are certainly not shy about showing off their love for each other on the red carpet! 

Among their more passionate public moments: this steamy smooch at the Met Gala earlier this year.

6. Keith's swoonworthy marriage advice.

"Dating. Keep dating your wife -- that’s it," the singer told ET, admitting that he's never stopped trying to woo his wife. "I'm still trying to get her to go out with me." 

7. Nicole keeps it real.

The actress had a perfectly practical and sweet response when asked how the pair keeps their romance alive. (Also: can we please talk about those heart-melting smiles they exchange before answering?!)

"As much as we love each other, we really like each other," Nicole told ET. "I'm speaking for myself, but that is a huge part of being married. Always, the first person I want to share anything with is him. It's true." 

8. They make time to celebrate their love, even when Keith's on tour.

Just last year, the duo rang in their ninth wedding anniversary with a low-key date night on Keith's tour bus.

"We had dinner on our bus. It was sweet," Keith told ET. "It was like we were dating still. It was great."

Hm... we're definitely sensing a theme here!

On their 10th anniversary, Keith is scheduled to perform in Mansfield, Massachusetts, before taking a week off from his Ripcord world tour. Perhaps he has something a little more extravagant planned for this year's milestone?

9. They're each others' greatest cheerleaders.

With both Keith and Nicole achieving massive career success separately, it's rare to see either one without their other half at a major red carpet event. Keith's a staple at Nicole's acting awards shows, and vice versa for all the high-profile music events.

"I told the girls I'm taking mom to the ball," Keith adorably admitted to ET at the 2015 Oscars. "I love it," he added of their jam-packed awards show schedules.

"We also like curling up on the couch, ordering sushi and watching it on TV," Nicole chimed in.

10. Love letters for days!

As if his lyrics weren't romantic enough, Keith is also apparently an avid writer of love letters for his wife!

"For every single night he's away, he leaves me a love letter," Nicole told InStyle in 2014. "Every single night of our relationship."

Even better, though, is when Nicole and the couple's daughters are able to join Keith on the road. "That's basically how I've seen most of America, on that bus," Nicole said.

"Keith and I are both gypsies at heart. We can make our home wherever we are," she continued. "The girls are like that too now, so we take them everywhere."
