Kate Middleton may be one of the most famous women in the world, but here are some lesser known facts.

She’s one of the most famous women in the world — a duchess, a devoted mother to three kids, a style icon whose fashion sense sets trends, and a queen in the making who has already worn some seriously breathtaking royal tiaras and necklaces. We all watched her get married in a fairy tale wedding after Kate got engaged to a future king who gave her one of the most iconic pieces of jewelry ever made.

Yeah, we know a lot about Kate Middleton.

But there’s so much more to learn, and just a little digging will bring up some of the lesser known facts about the Duchess of Cambridge — a must for every royal fan following the life and times of a woman who will be in the public eye for the rest of her life.

Kate hasn’t exactly been an open book when it comes to sharing details about her life, past or present. She and her family and circle of friends were tight-lipped for the roughly eight years Kate dated William, and for the first few years of her married life, we saw her more and more. Kate’s engagement video with William remains her only ever broadcast interview — though she participated in a palace-approved documentary for Queen Elizabeth’s 90th birthday. Even her cover for Vogue’s 100th anniversary was just a set of pictures with no story.

Little by little over the years, Kate has opened up and dropped little nuggets about her life, whether in casual conversations with charity officials and others at nonprofit events that she visits, or in rare speeches. Former classmates and even Kate’s mom, Carole Middleton, have dropped other little bits and pieces about the duchess — as well as royal biographers who have written books on her.

So what have we learned? Well, read on to find out. Here are 20 facts to know about Kate Middleton.
