Duke of Cambridge breaks silence on Duchess's pregnancy Attending a charity tennis gala on Saturday night, the Duke said that the Duchess of Cambridge was beginning to feel better after suffering from acute morning sickness, which saw her hospitalised for three nights earlier this week. The Duke was the guest of honour at the Winter Whites Gala in aid of Centrepoint, the homeless charity, of which he is patron. Speaking to Michael O'Higgins, the former chairman of Centrepoint, the Duke joked about the inappropriate name of his wife's recent illness. He said: "I don't know why they call it morning sickness - they should call it all day and all night sickness. It's a long old process but she is getting there. She feels like it is going to go on forever. The Duke had been due to attend the event at the Royal Albert Hall in London with the Duchess, who is continuing to recuperate at Kensington Palace after being discharged from hospital on Thursday. Guests who attended included Tim Henman, John McEnroe and the world number one tennis player, Novak Djokovic.
