The 'Big Little Lies' star also spills the secrets to how they've kept the romance alive for over a decade.
After nearly 11 years of marriage, Nicole Kidman is still head over heels for her husband, Keith Urban.
Her Big Little Lies character, Celeste Wright, may not have had a picture-perfect relationship, but off-screen, the 49-year-old actress' love life is, well, pretty impeccable.

While spilling her best beauty secrets with Australia's Who magazine, Kidman revealed that although she enjoys getting glammed up every now and then, she noted that the "Blue Ain't Your Color" crooner actually loves seeing his leading lady au naturel.
"He always prefers a natural me," she explained. "He's like, 'Come on, take the makeup off!"
The outlet also asked Kidman when she thinks Urban is most beautiful, and her answer was simply adorable.
"He's gorgeous when he's on the beach. He's a surf boy, my Aussie beach boy," she gushed. "And, oh, when he's playing his guitar."
Keeping their marriage strong and the romance alive after all these years is rare in Hollywood, but Kidman says it all comes down to friendship -- if you want to make it work, marry someone who you never have to doubt.
"That's what Keith and I have as well," she said. "As much as we have a love, we also have an incredible friendship and trust."
