Actress Nicole Kidman says she can eat "anything" she fancies, but in moderation.

The 47-year-old says she doesn't follow a strict diet, reports femalefirst.co.uk.

"There's certainly no secret regime. I wish there was. I'm actually not that strict with my diet. I pretty much eat anything, but all in moderation," she said.

"Likewise with fitness, I try not to be too strict with it and mix it up to make sure it stays fun," she added.

Kidman also tries to incorporate exercise into her busy life by doing something active - such as a bike ride or hike - with her daughters Sunday, 5, and Faith, 3, and her husband Keith Urban.

She said: "I'm sure all working mothers can relate to how hard it is to juggle a family while keeping healthy through diet and exercise! That's why I'm a fan of all types of training. I run, ride my bike, do yoga, whatever I can do and wherever I am in the world.

"We try to exercise as a family, which makes it much easier to squeeze in among everything else and, of course, much more enjoyable," she added.
