UPDATE: Royal Family Welcomes Baby Boy
Harry and Meghan, the Duke and Duchess of Sussex, have a new bundle of joy.
They have welcomed a new baby boy into the family.
In a brief media appearance, Prince Harry said, "This little baby is absolutely to die for. So I'm just over the moon."
Harry says he's over the moon after the healthy baby boy came into the world at 5:26 local time weighing seven-pounds, three-ounces.
The couple is still working on a name.
Harry told reporters gathered outside Windsor Castle that he was present for the birth, which he said was an amazing experience.
The pending birth was kept private, at the couple's request, until an announcement was made on Twitter that, "The Duchess of Sussex went into labour in the early hours of this morning."
The duchess is a 37-year-old retired American actress formerly known as Meghan Markle.
The 34-year-old prince is the son of Prince Charles -- next in line for the throne -- and Princess Diana, who died in a Paris car crash in 1997.
Congratulations are flowing in from across the United Kingdom.
British Prime Minister Theresa May tweeted: "Congratulations to the Duke and Duchess of Sussex on the arrival of their baby boy. Wishing you all the best at this happy time.''
Kind words also poured in from Justin Welby, the archbishop of Canterbury, Harry's uncle, Prince Andrew, and opposition Labour Party leader Jeremy Corbyn.
First Minister Nicola Sturgeon of Scotland also sent her good wishes.
The infant is now the seventh in line to the British throne.
Officials say senior royals including Queen Elizabeth II have been informed of the birth, as has the family of his late mother, Princess Diana.
This is Queen Elizabeth's eighth great-grandchild.
