Mary's Beach Body Miracle: Her Easy Diet Trick

The princess looks better than many half her age.

Striding across a Sydney beach with a big smile and a beach body women half her age would kill for, Princess Mary looked on top of the world.

The mum-of-four has always been blessed with a killer body and natural beauty, but hitting the sand with husband Fred and their children – Christian, 12, Isabella, 10, and six-year-old twins Vincent and Josephine – during their Aussie Christmas break last week, the 45-year-old Aussie princess was looking hotter than ever.

Says an onlooker: ‘Mary looked better than most of the 20-year-olds on the beach – everyone was doing a double take, she looked amazing!’

Now, for the first time, New Idea can reveal the easy diet secret behind Mary’s amazing physique and looks – and it’s something any busy mum can do!
