Speaking on ITV's 'This Morning' she said: "I love yoga, I love pilates, I love walking with the kids going hiking going swimming.

"I love to do now more activities that I can include the kids in even if that's turning the music on at home dancing around the house and being silly I can get exercise in that way."

The former Victoria's Secret Angel went on to explain that her top tip for keeping your skin looking youthful and aging "gracefully" is maintaining a healthy diet and drinking lots of water.

She added: "I think that drinking lots of water I know people talk about it all the time it's really important. I believe in health as well and healthy skin is the most beautiful skin.

"Everyone has their way but if you give your skin the vitamins and anti-oxidants that it needs - you can get the results you need the natural way and you can age I believe gracefully if your skin has the right Nutrients."

The brunette beauty added that confidence is the best way to look beautiful and believes a person is most attractive when they are self-assured while still being "humble".

She said: "When you're confident and you appreciate who you are as a person in a humble way I think that that's really beautiful ".
