The 45-year-old actress describes herself as having fallen "madly, passionately in love" with Cruise during an interview with DuJour magazine. Kidman was only 23 when the two tied the knot, and they quickly became inseparable.
"I was reeling with Tom. I would have gone to the ends of the earth for him," she remembers. "We were in a bubble, just the two of us. We became very dependent on one another."
Their split came in 2000, and Kidman says she didn't see it coming. "Our life together was perfect," she claims. "It took me a very long time to heal. It was a shock to my system."
But heal she did. Kidman and Urban married in 2006 and have had two daughters together -- Sunday Rose, 4, and Faith Margaret, almost 2. She says she is thankful for how close their family is.
"My life changed," Kidman says of meeting Urban, calling him a "wonderful, caring man."
