Kate Middleton in labour

Kensington Palace: Catherine, Duchess Of Cambridge, Formerly Kate Middleton, In Labour [Breaking]

It’s official. According to a tweet from Kensington Palace, the royal “spare” is finally on its way. Prince William and Catherine, Duchess of Cambridge, otherwise known as Kate Middleton, are at the hospital awaiting the baby’s arrival.

This is baby number two for the royal couple. The Duchess gave birth to their son, Prince George, in July of 2013.

According to the Telegraph, the drive from the Duchess’ residence at Kensington Palace to the hospital is a mile and a half.

The Duchess of Cambridge is several days overdue. She told a well-wisher a few weeks back that she was due mid- to late-April. Kensington Palace’s official Twitter page threw onlookers for a loop on Thursday by posting what appeared to be a baby announcement.

It turned out to be a “Throwback Thursday” picture of the birth of Prince George.

The new royal baby, born as it will be in early May, comes just days after the celebration of The Duke and Duchess of Cambridge’s anniversary. The son of Prince Charles and the late Princess Diana, Prince William, married Kate Middleton on April 29, 2011, an occasion that Kensington Palace also recalled earlier this week.

Unlike many other families, who know and announce the gender of their babies well before birth, the couple has yet to reveal whether they are expecting a boy or a girl.

There has been much discussion as to whether Prince George will have a younger brother or sister. Apparent clues of the baby’s gender included that Kate seemed interested in the girls’ clothes during a recent shopping trip in Chelsea. A clairvoyant also told a British paper she’s communicated with Princess Diana’s spirit, and the royal grandmother says it is a girl. Then again, Kate was seen wearing a blue coat, which, according to observers, might mean another boy is on its way.

If William and Kate are hoping for a daughter, they may still have a chance. Kate Middleton once said she wanted to have three children, as she is one of three.
