Last night Prince William hosted an event at Windsor Castle and the guest list wasn't quite what you would expect.
Kate Moss, Cara Delevigne and Mario Testino were all in attendance. Who knew Wills was such a fashion buff?!
The Duke of Cambridge's event was to celebrate the work of The Royal Marsden and was incredibly star-studded with the likes of Emma Watson, Benedict Cumberbatch and Cate Blanchett all making an appearance.
Sadly Kate Middleton didn't attend the event as she is still on maternity leave so no doubt spent her evening with the adorable Prince George watching Don't Tell The Bride Magaluf special.
Naturally, as the host, Prince William wandered round the room chatting to his guests but we would love to have been a fly on the wall for his conversation with Kate Moss.
