Prince William has sparked speculation following Kate's nod to Princess Diana. The Princess of Wales performed a solo engagement at the Royal Marsden Hospital on Tuesday, marking the occasion with a meaningful new addition to her jewellery collection.

There’s been a major shift in Prince William’s body language. Maybe he’s relieved that his wife Kate Middleton’s cancer is in remission. Or perhaps he’s thrilled about his brand-new roles. Or maybe his growing beard has given him a new wave of confidence.

Kate and William, the Prince and Princess of Wales, confirmed their patronage of the hospital where she had cancer treatment, the Royal Marsden Hospital in London.
