The new royal baby has arrived!
Prince William and Kate Middleton welcomed their third child — a prince — on Monday, Kensington Palace announced.
“Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 1101hrs,” the statement said. “The baby weighs 8lbs 7oz. 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 and members of both families have been informed and are delighted with the news,” the statement continued. “Her Royal Highness and her child are both doing well.”
Big brother Prince George, 4, was at school when his little brother was born and big sister Princess Charlotte, who turns 3 in May, was at home at Kensington Palace.
The name of the baby boy will be announced in due course, the palace said. Albert and Arthur are tied as the most popular names for a boy – at 5-1 and 9-1, respectively, according to British oddsmakers.

The self-proclaimed Royalist Town Crier walked up to the famous steps of the Lindo Wing and called out, “God Save the Queen,” and announced the birth of the baby prince.
The newest royal family member was born at St. Mary’s Hospital in London – just like George and Charlotte. Kate was admitted to the hospital before 6 a.m. (U.K. time) in the early stages of labor on Monday.
The royal baby is the fifth in line of succession after Prince Charles, Prince William, Prince George and Princess Charlotte.
Per royal protocol, an official announcement will be posted with the full details on an easel in the forecourt of Buckingham Palace.
It’s expected that close relatives – led by Kate’s parents, Carole and Mike Middleton, and William’s father Prince Charles and his wife, Camilla, Duchess of Cornwall – will come to see the couple and their as-yet-unnamed newborn before the couple leaves the hospital.

Following the celebratory formalities, including a gun salute in one of the London parks, the couple is expected to take their baby home to nearby Kensington Palace, where great-grandmother Queen Elizabeth may then visit.

As the couple takes in their first moments with the new baby, royal fans have gathered outside the hospital in hopes of another mini press conference like the one William and Kate held to debut George and Charlotte.
Just as with her first two pregnancies, Kate, 36, battled acute morning sickness, also known as Hyperemesis Gravidarum, during her first trimester. Once she resumed her royal duties, she hit the ground running, supporting World Mental Health Day, welcoming future sister-in-law Meghan Markle for the holidays, joining William for their busy tour of Sweden and Norway and walking the red carpet at the British Academy of Film and Television Arts Awards (just to name a few royal outings!).
The baby’s arrival comes just weeks before Prince Harry and Meghan Markle are set to tie the knot at St. George’s Chapel at Windsor Castle.
Let the royal baby countdown begin!
Kate Middleton arrived at the hospital to welcome her third child with husband Prince William, the palace confirms Monday.
“Her Royal Highness The Duchess of Cambridge was admitted to St. Mary’s Hospital, Paddington, London earlier this morning in the early stages of labor,” the statement reads.
“The Duchess travelled by car from Kensington Palace to the Lindo Wing at St. Mary’s Hospital with The Duke of Cambridge.”
The royal mom was admitted before 6 a.m. (U.K. time) to the same hospital where she gave birth to Prince George and Princess Charlotte.
The new royal baby will be the fifth in line of succession after Prince Charles, William, George and Charlotte. Prince Harry — currently fifth in line to the throne — will be bumped to sixth in line.
The news comes just days after members of the royal family gathered to celebrate the Queen’s 92nd birthday with a concert bash at London’s Royal Albert Hall on Saturday night. Kate was absent from the festivities as she her due date neared.

A group of devoted royal fans have been camped outside the hospital since April 9 in anticipation of the royal baby’s birth. Terry Hutt, 83, and John Loughrey, 63, are among the supporters who have a clear view of the famous door to the Lindo Wing, where Will and Kate will debut the royal baby.

“I know the routine so we wanted to get here for the best view,” Hutt tells PEOPLE. “We’re excited, over the moon.”
For Loughrey, who has wanted the birth to occur on St. George’s Day, is crossing his fingers that Kate does indeed have the baby on the national day of England today.
“I had a sense it was going to be today,” he says.
Adds Hutt: “We are going to celebrate later with fish and chips.”

The soon-to-be mother of three first announced her pregnancy in September in a statement from the palace.
“Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child,” the statement read. “The Queen and members of both families are delighted with the news.”

Just like her previous pregnancies, Kate suffered from Hyperemesis Gravidarum during her first trimester, which led her to miss Prince George’s first day of school. But she resumed her royal duties by her second trimester, keeping up a busy schedule until the weeks leading up to the birth. At an event in February, Kate joked that William was “in denial” ahead of the arrival of their third child.

Kate gave birth to daughter Charlotte in May 2015 only two-and-a-half hours after being admitted to the hospital. And just 10 hours after she gave birth, she appeared on the hospital steps looking stunning as she introduced the baby princess to the world.
The arrival of Will and Kate’s third child could be historic: If the baby is a boy, he will not displace big sister Charlotte in the line of succession, thanks to a measure that passed just after Will and Kate’s 2011 wedding. Up until this change, a younger son would usurp his older sister’s place when it comes to inheriting the throne.
KATE Middleton gave birth to her third child on April 23, 2018.
But these are the unusual royal birthing rules that the Duchess of Cambridge had to follow in order to adhere to tradition. Here's the lowdown...

The royal family has a set of customs they follow when any baby is born – including who the first person to be told the news is.
Other practices dictate who is allowed in the birthing room and how the birth is announced to the British public.
1. The Queen has to be the first to know
The Queen must be told a child has been born into the royal family before the news is announced publicly.
It's reported that Prince William rang his grandmother on an encrypted phone when Prince George was born.
Traditionally, the announcement has always been on an easel outside Buckingham Palace.
Kate and William broke this protocol and announced it on Twitter with Prince George.

2. The town crier announces the news to the public
Town crier Tony Appleton announced the births of both Prince George and Princess Charlotte.
This custom harks back to medieval times when people couldn’t read or write.
3. Home births are preferred
As is tradition, the Queen gave birth to all of her children in Buckingham Palace.
Princess Diana broke this rule and gave birth to sons Prince Harry and Prince William at London’s St. Mary’s Hospital in the private Lindo Wing.
Kate also had her three children at this hospital.

4. Dads are banned from the birthing room
Giving birth is considered a female-only event and fathers are not allowed in the delivery room.
This rule is believed to have been relaxed after the birth of Prince Charles.
