Prince William has rushed to be by his wife, Catherine's side as she battles severe morning sickness.
The 34-year-old suffers from a condition called Hyperemesis Gravidarum, meaning she struggles with the same extreme morning sickness she endured with her previous two pregnancies.
Kensington Palace confirmed Catherine was pregnant yesterday when she was forced to cancel an appearance at a charity event.
'As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum. Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today,' the palace confirmed in a statement.
'The Duchess is being cared for at Kensington Palace.'
In the same statement, the palace also confirmed she and Prince William were expecting their third baby.
“Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child,” a statement from Kensington Palace said.
“The Queen and members of both families are delighted with the news.”
