The 'Cold Mountain' star married Tom in 1990 and the 'Top Gun' star left her just before their tenth wedding anniversary, although they remained husband until 2001.

Nicole, 39, told Vogue magazine: "Honestly, I would have stayed married for the rest of my life. It's not like I regret who I was in that marriage, I don't at all. It was eleven years of my life. It wasn't 50 years, it turned out to be 11.

"You get the advice, 'Don't get married when you're 22', and you just think, 'They don't know what they're talking about!' But now I look back and think, 'Oh, there's probably some truth to that.'"

The Australian actress was pregnant when Tom left her, and she suffered a miscarriage shortly afterwards. Their marriage was dissolved for undisclosed reasons in 2001.

Nicole also spoke about meeting her current husband Keith Urban, who she married this summer.

She said: "I was very wary, and damaged. It wasn't that I'd give up hope, I was, just, asleep. But now I feel like I've woken up again. Rather than living through characters, I've learned to be myself."

Recovering alcoholic Keith checked into rehab last month after falling off the wagon while Nicole was away filming 'His Dark Materials'. The actress flew home to Nashville to be with her husband.
