Elle Macpherson doesn't know how much she weighs.
The 50-year-old supermodel - who is nicknamed 'The Body' - doesn't concern herself with her size because it often fluctuates without people noticing and she would rather feel good than worry about being slim.
She said: "I don't look at my weight - I don't even know how much I weigh.
"It's about how I feel, my energy levels and creative levels. Those are more important to me than a number on a scale.
"When I was younger I was more concerned about what I weighed because I didn't know any better. I can fluctuate five to 10 pounds and most people don't even notice it.
"Sometimes I can be heavier but feeling really great. I'd rather be feeling great than worrying about how much I weigh."
While she doesn't worry about her weight, Elle is passionate about working out and finds a way to be active every day.
She told OK! magazine: "Sport is really important to me. At the moment I love swimming. I live in Miami and we have a pool so it's easy for me - I also like waterskiing and windsurfing and I really love hiking too.
"Whenever I travel I always try to find something to climb, whether it's a mountain or a bush trail. It's like meditation for me.
"I try to do between 25 minutes and an hour of exercise a day. I schedule it in my diary every morning like a business appointment to make sure I stick to it."
