Prepare for the onslaught of new British Royal collectible tea sets, plates, shirts, hats, etc. -- 'cause the Royal great-grandbaby is due any minute.
The Queen's people have released a statement saying Kate Middleton is officially in labor at a hospital in London.
Hundreds of Brits have already taken to the streets to await their new master.
The Monarchy is still not saying if the new baby is a boy or a girl.
We know ... once Kate pops out the little squirt, a document will be signed by a member of the official royal medical staff and driven under royal escort to Buckingham Palace.
The medical document -- which will contain the fundamental birth info (sex, weight, time of birth) -- will be displayed on an "ornate easel" at the palace.
We're told the name will not be released straight away.
Stay tuned ... we'll have the news as it emerges from Kate's vagina.
