Nicole Kidman has shared her sentiments on her enduring 18-year marriage to musician Keith Urban as she expressed gratitude for their relationship, describing it as a source of profound love and luck in her life.

While conversing with PEOPLE for the magazine’s 50th-anniversary special issue, the Oscar winner said, "I'm so lucky that I have Keith who's just my love, my deep, deep love.”

"It was my [38th] birthday, and he stood outside with gardenias at 5 a.m. on my stoop in New York," Kidman added.

She continued, "That is when I went, 'This is the man I hope I get to marry.'" Calling that time "pretty intense," the Big Little Lies actress admitted she had found "the one" really fast.

Kidman revealed, “"I believed by that point he was the love of my life," adding, "Maybe that’s because I am deeply romantic, or I'm an actress, or I have strong faith as well, but I just believed, 'Oh, okay, here he is.'"

The Expats star also noted, "I remember talking to somebody once and they were like, 'What do you do?' I'm like, 'Well, primarily I have my family, I raise my kids, and I work'.”

Nicole Kidman married the country music star in 2006 and since then they have been madly in love with each other.
