Nicole Kidman has claimed she eats ''anything.''

The 47-year-old actress insists she doesn't follow a strict diet and will gorge on what ever she feels like, but she makes sure she doesn't over-indulge.

She explained to the Los Angeles Times: ''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.

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

Nicole also tries to incorporate exercise into her busy life by doing something active - such as a bike ride or hike - with her daughters Sunday, five, and Faith, three, and her husband Keith Urban because she struggles to juggle a gym routine with her demanding career.

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.''
