Nicole Kidman has admitted she barely knew Keith Urban when she decided she wanted to marry him one month after they started dating.

"I'm spontaneous. I jump in. I kind of like getting married and then getting to know each other," the actress revealed to Elle magazine.

"I know that it sounds incredibly strange, but to me, it’s a more natural process."

The couple, who met at the G'Day LA event in January 2005, tied the knot in July 2006 and despite a rough patch shortly after when Keith entered the Betty Ford Center for addiction, their union has grown rock solid and they recently celebrated their eighth wedding anniversary.

The 47-year-old, who is mum to daughters Sunday Rose, six and Faith Margaret, three with Keith, and adopted children, Bella, 22, and Connor, 19, from her previous marriage to Tom Cruise, also spoke about wanting more kids.

"I had my last one at 43. My grandmother had her last at 49. Every month, I'm like, 'I hope I’m pregnant!'… I wish I was!"
