Some are convinced the royal due date has already passed for Prince William and his wife to have their first child, the future heir to the English throne, though Buckingham Palace has not given an exact date.
Many in the British media predicted the baby would be born last week, and the Prince himself is now on official leave.
Dozens of reporters have staked out the Central London hospital where Kate is expected to give birth. The palace has said only that the Duchess is due to deliver the baby in "mid-July".
