Is the Duchess of Cambridge having a boy or a girl?  Supposedly even they do not know, waiting until the birth to find out the sex of their baby.

Kate Middleton is now officially a day overdue as the world awaits the debut of the newest royal.

Her last official public ceremony was the Trooping the Colour Ceremony during Queen Elizabeth II's Birthday Parade on the balcony of Buckingham Palace.

Royal watchers say Catherine is expected to take about three and a half months off for maternity leave before returning to her royal duties.
