Pregnant Kate Middleton and Prince William

The royal baby watch is over! With her due date of July 11 coming and going, the most anticipated baby of the year has made its arrival. Kate Middleton and Prince William have welcomed a baby boy on July 22.

“Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 4.24 pm,” reads the announcement from the Twitter page of the official website of British Monarchy.

"The baby weighs 8lbs 6oz. The Duke of Cambridge was present for the birth. The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry & families have been told and are delighted.”

The official announcement went on to say that Kate will stay in the hospital. “Her Royal Highness and her child are both doing well and will remain in hospital overnight.”

The royal baby name?

A source said that Prince William and Kate “may take some time” to pick the perfect baby name for the future king of England. It actually took a week before Princess Diana announced the name of Prince William. It took one month for Queen Elizabeth and Prince Philip to name Prince Charles!

We do know that his official name will be His Royal Highness (name), Prince of Cambridge.

The baby is third in line to be the king of England, behind his father Prince William. William’s father, Prince Charles, is first in line.

Celebrities that share the same birthday with the royal baby boy include Selena Gomez, John F. Kennedy’s mother Rose Kennedy, David Spade and The Outsiders author S. E. Hinton.

Kate’s lavish delivery room

Kate checked into the hospital at 5:30 a.m. on July 22 at the posh Lindo Wing at St. Mary’s Hospital. Middleton, 31, was planning on giving birth naturally to the baby — however no word yet on her actual delivery.

The Lindo wing was the same place that Princess Diana delivered Prince William and his brother Prince Harry! The Lindo Wing has a history of many royal births, including Princess Anne (Prince Charles’ sister) who delivered Peter and Zara Phillips at this same hospital.

The Lindo Wing — which underwent a renovation in 2013 in preparation for the royal baby — has not only a catering staff, but individual birthing rooms with birthing pools as well as satellite TV. The reported cost of giving birth at a private suite is over $9,000, reports the Daily Mail.

Kate’s sister, Pippa Middleton, and mom Carole were reportedly not in the delivery room with her as she gave birth to the royal baby. “Buckingham Palace denied rumors that they were going to be in the delivery room with Kate. She very much wants just her husband to be there," NBC reports.

Prince William is undoubtedly wishing his late mother, Princess Diana, could be there to share his joy in the birth of his first child. Kate told NBC News she wished she could have met her. "I would have loved to meet her. She was an inspirational woman to look up to," Kate said.
