Keith Urban and Nicole Kidman are one of country music's most beloved couples, and Kidman is opening up about one of her most romantic memories shared with her husband.

In an interview with W Magazine, the actress tells the story of the time Urban pulled off an amazing stunt for her 40th birthday when he took her up to the top of a small hill in Australia for a surprise fireworks display. "He sat me down, and he had put together this huge firework display," she reminisces. "And I sat there and watched, like fireworks that would've cost a fortune, and it was just for the two of us. It was sexy."

She also talks about a few of her pet peeves, saying the she "gets anxious" when Urban doesn't answer her phone calls, so she has to keep calling back until he does. "I don't like that," she says giggling. The star turns 50 in 2017 and reveals that she feels a bit fragile at times. "I'm raw," Kidman admits, calling herself "impressionable." "As I get older, I get more exposed and sort of vulnerable I think, which isn't a bad thing."

Country's Cutest Couples Kissing

The star couple recently appeared together at the 2017 Golden Globe Awards where Kidman was nominated for Best Supporting Actress in a Motion Picture for her role in the film Lion. Her husband, meanwhile, scored himself the most nominations at the 2017 ACM Awards after they were announced on Thursday (Feb. 16), appearing in categories such as Entertainer of the Year, Male Vocalist of the Year, Album of the Year and more.
