Kate and Harry's VERY special bond: From watching Game of Thrones together to advising on his love life - how the future Queen became the sister that the young prince never had

It's becoming rather hard to ignore how well Prince Harry gets on with the Duchess of Cambridge. Whether it's at the London Olympics, weddings, Trooping the Colour or even sombre events like the World War I centenary commemorations in Belgium in 2014, Harry and Kate can often be seen side-by-side. Harry is, of course, a joker, and likes to give humorous asides during some public events, like his grandfather. And Kate is a polite, responsive soul, not one to ignore others' attempts to make her laugh. Regardless, the closeness of their relationship is all too apparent. Harry has plenty of female friends - including cousins Zara, Beatrice and Eugenie - but he is probably closer to Kate than any other woman on the planet. Theirs is a genuine friendship, founded on nights spent in front of Game Of Thrones boxsets and companionable suppers. From giving him cookery lessons to offering sensible romantic advice, Kate has become Harry's lynchpin.
