The Duchess of Cambridge has left the hospital after being treated for a severe case of morning sickness.

The former Kate Middleton appeared happy as she left the King Edward VII Hospital Thursday along with her husband Prince William.

Officials for the Royal Family said Kate would head to Kensington Palace in London for a period of rest.

Prince William had been spending a significant amount of time at the hospital and visiting his wife every day.

Media from around the world also camped outside the hospital, awaiting any news on the royal pregnancy.

Reports indicate Kate is less than 12-weeks pregnant with her first child.
