Kate, who is a mum-of-three, married Prince William back in 2010 - and she is returning to the spotlight this year after battling cancer and having chemotherapy.

Tom Parker Bowles, the Queen's only son, hosted a charity event this week to raise money for the Royal Marsden in memory of a young mother-of-two.

Charlotte, who is Prince William's only daughter with his wife 42-year-old Kate Middleton, is the middle child of the pair, who share three between them.
