Michelle Pfeiffer keeps super-slim by eating doughnuts.

The stunning 49-year-old actress, who is renowned for her sexy slender figure, insists there is no big secret to keeping in shape and admits she indulges her craving for calorific treats whenever she feels like it.

She said: "It's simple. Eat well, exercise and get lots of sleep but make sure you indulge occasionally. At my age I think, what the hell, and eat a Krispy Kreme doughnut!"

Sugary snacks are not the only junk food Pfeiffer - who famously donned a skin-tight PVC catsuit to play super-villain Catwoman in 'Batman Returns' - likes to gorge on.

She added: "My other thing is crunchy, salty food. I love chips, salsa and guacamole."

Pfeiffer also has some words of advice for any women who are stressing about their weight or considering going under the surgeon's knife to change their appearance.

She said: "I don't believe men want women to have grotesque plastic surgery or be undernourished and bony. All the plastic surgery in the world can't stop you getting older."
