"I was so young when I got married. I look back now and I'm like, 'What?'" Kidman told Red magazine, reports people.com.

She added: "You look at Taylor Swift, I mean how old is she? She's 26. I had two kids by the time I was 27 and I'd been married for four years. But that's what I wanted." 

Kidman, 49, married Cruise in 1990 after meeting him on the set of "Days of Thunder". They later adopted two children - Isabella, now 23, and Connor, now 21. 

The Oscar-winner is now married to country star Keith Urban.
