Camilla, the Duchess of Cornwall

Britain's Duchess of Cornwall is "immensely looking forward" to the birth of the royal baby.

Camilla insists she and husband Prince Charles can't wait for the phone call to say Prince William and Duchess Catherine's little one, who is due tomorrow (13.07.13), is on his or her way into the world.

When asked yesterday (11.07.13), at the Coronation Festival in the grounds of Buckingham Palace, if she was on "tenterhooks" waiting for any news, the duchess replied: "Yes, we are very excited - immensely looking forward to it and waiting for the phone call."

Friends have revealed Duchess Catherine - who was known as Kate Middleton before her and Prince William's nuptials - is "feeling really well" and very nearly attended last night's event, which celebrated the best of British business.

Richard Palmer, royal correspondent of the Daily Express newspaper, wrote on Twitter: "Friends say Kate's feeling really well and at one stage today was even thinking about going to tonight's Buckingham Palace concert.

"In the end Kate decided to stay home but her parents and siblings were in the VIP section at tonight's concert along with the royals."

Charles and Camilla were joined at the event by Catherine's mother and father, Carole and Michael Middleton, as well as her brother and sister, Pippa and James Middleton, who watched proceedings from the royal box at the back of Buckingham Palace.

Catherine is due to give birth in the private Lindo Wing at St. Mary's Hospital in London's Paddington tomorrow.
