Nicole Kidman struggled to cope with life when she was single. The Oscar-winning actress felt "lonely" and "isolated" until she met country singer Keith Urban.

Nicole, who married Keith last year, told Britain's Daily Mirror newspaper: "When I was alone I became very isolated and felt very lonely and it was difficult to meet someone."

"I realized you can have so many beautiful things around you and if you don't have someone in your life to share it with, it doesn't mean that much."

"We were two lonely people who met at a time when we could open up to each other. We were a mixture of frightened and brave. It's hard when you are alone."

Nicole - who has two adopted children, Isabella, 14, and 12-year-old Connor with ex-husband, actor Tom Cruise - also revealed how proud she is of Keith after he successfully completed a 90-day stint in rehab for alcohol addiction last year.

The 'Moulin Rouge' star said: "I'm just so grateful I have someone I can share the highs and also the lows with."

"I love him for his honesty and bravery. Simply put, he's a wonderful, wonderful man and I'm very lucky to have him."
