Kate's supposed to be taking time off from official duties to focus on her recovery from hyperemesis gravidarum, but this one might be tough to turn down.
A 21-year-old with just months to live has identified her wish to meet William and Kate as one of the last outstanding wishes to be fulfilled on her 'bucket list' of things to do before she dies - along with a parachute jump, to have a hen night, to open a bottle of champagne with a sword and take her mum to see Wicked at the theatre.
The inspiring bravery of Stephanie Knight, who has been battling cancer since the age of 17, is now causing a viral campaign on Twitter for her to meet Will and Kate, with the hashtag #StephanieKnight.
Stephanie was diagnosed with Ewings sarcoma in 2009 after doctors found a tumour the size of a tennis ball in the back of her pelvis, accordign to the Daily Mail.

Stephanie has already helped to raise more than £40,000 for the Teenage Cancer Trust since 2009 - the charity which funded Ward C9 at Addenbrooke's Hospital.This is Stephanie's full wishlist from her personal website:
