World celebrates birth of Britain\'s royal baby boy

Fans across the globe are celebrating the news of Britain's new royal baby.

U.S.-born former actress Meghan Markle gave birth to a boy on Monday (May 7) morning, weighing 7 pounds 3 ounces.

Beaming father Prince Harry told reporters both mother and child were doing well.

SOUNDBITE (English) PRINCE HARRY SAYING: "It was amazing, absolutely incredible.

As I say, I am so incredibly proud of my wife and, as every father and parent would ever say, your baby is absolutely amazing, this little thing is absolutely to die for." Harry, Queen Elizabeth's grandson, was present for the birth.

And Doria Ragland, Meghan's mother, was with the couple at their home, Frogmore Cottage, on the estate of Windsor Castle.

Harry and Meghan took to Instagram to announce the news.

But following a tradition dating back at least to 1837, a notice announcing the birth was posted on a ceremonial easel on the forecourt of Buckingham Palace.

Congratualtions for the Duke and Duchess of Sussex have poured in from family, celebrities and political figures.

The baby is the eighth great grandchild of the 93-year-old queen.

And is the first mixed-race baby born into a senior position in British royalty, according to royal experts.

The child could be entitled to hold joint British and American citizenship according to nationality rules.

But won't automatically be a prince.

It's up to the Queen to bestow any such title by issuing what is known as a letter patent.

The seventh in line to the throne does not yet have a name.

And you'll have to wait a bit longer for that first glimpse of the newborn.

Unlike his brother and wife Kate, who stood on the steps of the hospital within hours of the birth of their three children... Harry and Meghan are expected to take part in a limited photo call in the grounds of Windsor Castle in the next couple of days.
