According to Us Weekly, Middleton and her hubby unexpectedly left Bucklebury -- a village in West Berkshire, England -- with police escort at approximately 3 p.m. local time on Friday.
Just Jared reports that the couple is awaiting the final hours of her pregnancy at Kensington Palace in London. The palace is close to St. Mary's Hospital, where Kate is expected to give birth.
A tweet was sent out Friday by Breaking News reporting that police presence has been beefed up outside the St. Mary's Hospital.
Since Middleton's due date was believed to be July 11, the royal kidlet should arrive at any time.
