It's official: the newest member of the royal family is a boy. The as-yet unnamed His Royal Highness Prince [future baby name here] of Cambridge was born at about 4:30 p.m. local time at St. Mary's Hospital in London, and weighing 8 lbs 6 oz. 

The news, in a shakeup to tradition, was announced first by press release:

The Duchess of Cambridge went into labor (or labour) earlier this morning, officially putting the world on notice for the new prince's arrival. The hundreds of reporters already camped outside St. Mary's finally got what they were waiting for early on Monday as the Kate formerly known as Middleton checked in to her maternity suite around 6:00 a.m. local time.

This picture, taken shortly after the news of Kate's arrival at the hosptial broke, gives you some sense of the scope of the assembled media awaiting the birth. And the crowd grew even more as as more reporters, tourists, and interested onlookers descended on the scene:

Jesal Parshotam, a freelance photographer staking out the hospital, explained to The Evening Standard, how he broke the news that the Duchess had arrived at the hospital, but passed up the chance to take a photo of her entering, saying "I made that decision — she’s a woman in labour. I just wanted to photograph the commotion and convoy of cars. That was a personal decision we both made. To take a picture of her would have been over stepping the mark."

Crowds also gathered at  Buckingham Palace, where the Queen awaited the news of newest great-grandchild.

As news broke that an announcement concerning the royal baby was imminent, the media frenzy already in high gear really started to get going. 

British and international leaders are lining up to congratulate the family on the new kid, who is now third in line to the throne. Here's a sampling of statements: 

The Queen: 

 "The Queen and Duke of Edinburgh are delighted at the news," reads a short statement, according to NBC News

President Obama:

"Michelle and I are so pleased to congratulate The Duke and Duchess of Cambridge on the joyous occasion of the birth of their first child.  We wish them all the happiness and blessings parenthood brings.  The child enters the world at a time of promise and opportunity for our two nations.  Given the special relationship between us, the American people are pleased to join with the people of the United Kingdom as they celebrate the birth of the young prince."

Prince Charles: 

Prime Minister David Cameron:

For those of you wondering why there's no baby name yet: the royal family has been known in the past to take its time choosing a name. So we might have to wait awhile to learn what it is (though we've helpfully handicapped some of their options). Meanwhile, the Duke and Duchess of Cambridge are expected to formally present the boy to the public in the next few days.  

The unnamed royal baby shares a birthday with (among others) Selena Gomez, Rufus Wainwright, rapper Petey Pablo, actor Rhys Ifans, former NFL player Keyshawn Johnson, pro wrestler Shawn Michaels, David Spade, John Leguizamo, Keith Sweat, Willem Dafoe, composer Alan Menken, Don Henley, author S.E. Hinton, Albert Brooks, Danny Glover, musician George Clinton, Alex Trebek, Terence Stamp, Tom Robbins, Oscar de la Renta, and Bob Dole.
