The Duchess of Cambridge's pregnancy sickness means she has cancelled an appearance at tomorrow's UK premiere of The Hobbit. Kate is suffering from the condition known as hyperemesis gravidarum which leaves expectant mothers with constant nausea and regular vomiting.
St James's Palace said:
"The Duchess of Cambridge will not attend The Hobbit premiere tomorrow evening and will continue to rest privately. The Duke of Cambridge will attend as planned."
The Duchess of Cambridge left hospital today, after three days of treatment for a severe form of morning sickness.
A nurse disclosed information about Kate's condition to two DJs who rang the hospital claiming to be the Queen and Prince Charles.
The Duchess of Cambridge is to spend another night in hospital being treated for acute morning sickness but is said to be feeling better.
