The United Kingdom's British Broadcasting System, BBC, unwittingly released a video of how reporters feel about the new royal baby, as Kate Middleton goes into labor.

"Plenty more to come from us — none of it news," a television reporter for the network told the anchorman, not realizing the feed was broadcasting live.

As reporters continued their watch, the Royal Duchess of Cambridge arrived at St. Mary's Hospital early Monday morning with her husband, Prince William, second in line to the throne of England.

Kate Middleton is expected to give birth in a private wing of the hospital, where Princess Diana gave birth to William and his younger brother, Harry, Prince of Wales. Crowds gathered outside Buckingham Palace to await the infant who will be third in line to the throne after Prince Charles, son of Queen Elizabeth II, and William.

The royal couple's spokesman said "things are progressing as normal," as Middleton continued to experience the early stages of labor. However, reporters didn't know whether the birth would be natural or by caesarian, or whether William would be in the delivery room.

The news marks the first time in history that three generations of royals would be in line for the throne, as the queen awaited news about her great-grandchild.

Although the royal family had kept Middleton's due date a secret, reporters estimated the birth to be approximately 10 days or so overdue.

According to Buckingham Palace protocol, a royal aide would soon emerge from the hospital with a signed bulletin on official letterhead to be given to an official who would then drive to the palace to place the announcement in public view in front of the building. Royal officials have announced family births in that manner since Prince Charles in 1948 and William in 1982, although royals will also make the announcement this time with social media.

The baby's sex is of particular interest to fans of the British royal family following an edict from the queen that, for the first time in history, a first-born girl would be eligible for the throne ahead of any little brother.
