The royal bun may be ready to come out of the oven.

After spending a week at the Middleton family home in the English countryside, pregnant Kate Middleton and husband Prince William abruptly left for London around 3 p.m. on Friday, according to Us Weekly, who reported it confirmed that all royal protection officers have also departed the Middleton home.

What about Bond ... James Bond. Where's he?

The website hasn't confirmed whether the 31-year-old duchess is headed for St. Mary's Hospital to give birth in the Lindo Wing, or simply back home to Kensington Palace. But, just for fun, let's pretend it's the former and all go on high alert.

A palace rep said, "We wouldn't comment on the exact whereabouts of the Duke and Duchess -- we wouldn't normally do so in their private time."

A royal source told Us Weekly on Friday that Middleton's due date has "passed."

The Royal Air Force says the 31-year-old Prince William hasn't begun his paternity leave, but is simply taking time off to await the birth of his first child. "We're all on the edge of our seats for news," a Royal Air Force source admitted. "I thought the baby would be born by now."

Well, maybe it has.
