Some of the royal family attended the Coronation Festival Concert at Buckingham Palace on July 11, but Prince William and Kate Middleton were not in attendance. The royal baby is due any day now.  Middleton's sister and brother Michael and Pippa were at the festival together along with their parents Michael and Carole.

"James, meanwhile -- at 26, the youngest of the brood -- was dapper in a dark blue suit, crisp white shirt, and red tie. He stuck close to his sister as they milled about the box, along with their parents, Michael and Carole," reported US weekly.

"The Household Division's Fanfare Trumpeters opened the gala event with a musical blast, followed by performances by pop act The Feeling and welsh opera singer Katherine Jenkins. During a break from the action, Queen Elizabeth II, Prince Charles, and Camilla, Duchess of Cornwall, retired for the evening; the Middleton family stayed for the entire duration of the concert."

The royal baby due date is looming and photographers are already lined up outside the hospital.

Prince William is now on standby at an air force base in north Wales,reports Reuters and ready to rush back to London if his wife goes into labor.

"The couple have remained vague about the exact date the baby is due other than to say mid-July and the arrival will be announced in a combination of the traditional and modern - via Twitter, websites and with a notice outside Buckingham Palace," reported Reuters.

The baby will be born in a wing of St. Mary's Hospital in London in a private wing called the Lindo wing. It's the same hospital that Prince William and Prince Harry were born.

The managing Editor of Majesty Magazine, Joe Little, said to Reuters about the couple that privacy was a major concern for them.

"Privacy is key for Prince William as he saw the way his mother, Princess Diana, suffered at the hands of the paparazzi, and he wants to make sure this does not happen to his wife or his own children," Little told Reuters.
