1:14 PM PT -- Prince William's daddykins -- Charles the Prince of Wales -- has just released a statement on the birth of the baby ... saying, "Both my wife and I are overjoyed at the arrival of my first grandchild. It is an incredibly special moment for William and Catherine and we are so thrilled for them on the birth of their baby boy."
Also, it sounds like he hasn't seen the baby yet ... because he added, "We are eagerly looking forward to seeing the baby in the near future."
12:53 PM PT -- THE DOCUMENT HAS ARRIVED!!!! And it doesn't say anything interesting at all, except that Kate "safely delivered of a son" and she and the baby are doing well. Woo-freaking-hoo.
12:45 PM PT -- The medical document is currently en route!!! WHAT WILL IT SAY?!?!?
It's official, Prince William has secured his heir ... and millions of Brits just spilled their tea ... KATE MIDDLETON GAVE BIRTH TO A BABY BOY!!!
According to Buckingham Palace officials, Kate popped at precisely 4:24 PM BST. The boy weighed in at 8 pounds 6 ounces.
After Prince Charles and William, the baby will become third in line to the British throne. Sorry Harry.
As we reported, a document will be signed any moment by a member of the official royal medical staff -- detailing the baby's birth info -- and it will then be driven under royal escort to Buckingham Palace, where it will be displayed on an "ornate easel." Smashing!
We still don't know the baby's name -- but we DO know he's got some iffy genes in the hair department, so we gotta ask ...
