Royal Baby Could Arrive "by the End of the Week," Camilla Says Credit: Chris Jackson/Getty Images The royal baby's future step-grandmother, Camilla, the Duchess of Cornwall, made what seems the be the clearest hint yet of when we can expect the royal baby at a public event today in Cornwall with her husband, Prince Charles. "We're all waiting at the end of the telephone," Camilla can be heard saying in a video from the event. The man standing beside Camilla made a comment about all the people camped out waiting for the baby to which she replied, "I think so, I think so. ... I think by the end of the week he or she will be there." Royal baby watch is in full swing. Observers believe the baby could come any day now because it is believed that Kate Middleton is due sometime in mid-July. The duchess reportedly spent the weekend with her family at their home in Bucklebury, which is about 60 miles west of London and St. Mary's Hospital, where Kate is expected to deliver. Prince William played in charity polo match on Sunday in Glouchestershire, nearly 100 miles away. Though astrologists, bettors and royal watchers have all made their predictions about when Baby Cambridge will arrive, it may be grandma who knows best.
