Kate Middleton, who's undergoing chemotheraphy for her cancer diagnosis, looks barely recognisable with golden blonde hair in unearthed photo with her sister Pippa Middleton.

The future Queen had golden blonde hair when she was a child. In the picture, Kate, four-year-old, is seen with her father Michael and sister Pippa in Jordan, where she spent the early years of her childhood growing up.

The future Queen Consort, who has done little by way of 'hair transformations' over the years, loves her signature chocolate brown locks as she has altered it slightly in the 13 years she's been married to Prince William.
Princess Kate's glossy brunette tresses have long been the envy of royal fans who have tried to uncover exactly how the royal achieves her signature healthy curls as there are few royals with hair quite as captivating as that of the Princess of Wales.
