Duchess of Cambridge to miss The Hobbit premiere

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."
