The Duke of Cambridge, Prince William, has broken his silence on his wife’s pregnancy and revealed that Duchess Kate is beginning to feel better after suffering from acute morning sickness. The royal broke this news at the Winter Whites Gala in aid of Centrepoint, the homeless charity, of which he is patron. The 30-year-old joked about the inappropriate name of his wife’s recent illness, which saw her hospitalised for three nights earlier this week.“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 Mirror quoted him as saying.
