"As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter."


It is unusual for a high profile (or any) pregnancy to be announced before 12 weeks but there has been speculation that Kate could be only around eight weeks pregnant. Rumour has it the couple had been keen to save their exciting news until Christmas Day but were forced to reveal the pregnancy after Kate fell ill.

Despite seeming on top form last week at the Natural History Museum and even playing a spot of hockey in heels at her former prep school, Kate developed this acute form of morning sickness over the weekend and was driven to hospital by William, where she has been put on a drip to prevent dehydration.

According to sources, Kate and Wills hadn't even had the chance to tell their close family, with many of the royal family finding out just an hour before the official statement was released. Prince Harry, who is currently serving in Afghanistan, was reached by email.

Kate will spend several days in hospital under medical supervision, but is said to be in good spirits and was able to walk unaided into hospital when she arrived. William, who has spoken in the past about his desire to be a dad, spent hours by her side and was photographed leaving the hospital yesterday evening.
