Well, not quite all...

Yes, the Duchess of Cambridge is expecting her second child. And the timing - when it comes to the Scottish referendum - could not be better:
PROJECT ROYAL BABY TO THE RESCUE! #indyref— Liam Houghton (@LiamHoughton) September 8, 2014
SHE'S PREGNANT SCOTLAND. YOU CAN'T LEAVE THE UNION NOW. #RoyalBaby— David Morgan (@thisisdavid) September 8, 2014
Classic campaigning by the No group, getting the Duchess of Cambridge pregnant. The Scots love a royal baby.— Tiahowler Biltawülf (@Biltawulf) September 8, 2014
SCOTLAND: If you vote No, Kate promises to bring the child up as a panda. #indyref— Zorro P Freely (@banalyst) September 8, 2014
Given today's news about the Royal Baby, I would like to ask the voters of Scotland: Can we come with you?— Jonn Elledge (@JonnElledge) September 8, 2014
Dear Scotland, Don't leave us now. Not with another baby to feed/clothe/bring up in a palace.— Sarah Vine (@Queenofjustice) September 8, 2014
++++ BREAKING +++++ New Royal baby set to be call Hamish McWindsor— MirrorJames (@MirrorJames) September 8, 2014
If they've got any sense if it's a boy they'll announce they're calling him Andrew. If it's a girl they'll call her, I don't know, Tunnock?— Gary Bainbridge (@Gary_Bainbridge) September 8, 2014
That's right - Twitter is already speculating over the royal baby's name:
We've had King, Queen, Prince, Princess and Boy George. Pretty sure the next one will be called Miss Dynamite.— Swissss (@Swissss) September 8, 2014
If the Duke and Duchess of Cambridge don't name their second child Sharky then they're just wasting everybody's time.— IncrediblyRich (@IncrediblyRich) September 8, 2014
But what will they call the new baby? Prince Albert has a nice ring to it.— Adam Kay (@amateuradam) September 8, 2014

Some people are already wondering how the news will affect Prince George:
Sibling rivalry can be intense, especially when you know your older brother is definitely going to get a better job than you. #royalbaby— Steve Bugeja (@SteveBugeja) September 8, 2014
I wonder if the new #RoyalBaby will get Prince George's hand-me-downs? Like his colletion of hand-crafted antique shotguns. And Cornwall.— cluedont (@cluedont) September 8, 2014
Very sensible plan to have a second #RoyalBaby. Only children are at risk of growing up with an overweening sense of entitlement.— Jack Seale (@jackseale) September 8, 2014
While others are feeling an affinity with the Duchess:
I'm not having a baby, but I did make an amazing lunch that I am very much looking forward to, so I know how Kate Middleton feels.— Periwinkle Jones (@peachesanscream) September 8, 2014
Of course, there's more than one angle on this story. The Daily Mail one...
Couple living in huge house at public expense get pregnant, costing us all money. Where's the Daily Mail when you need them? #royalbaby— Debbie Moon (@DebbieBMoon) September 8, 2014
And the tech one...
WHAT’S THE TECH ANGLE ON THE ROYAL BABY— Alex Hern (@alexhern) September 8, 2014
Which of course will be tomorrow's announcement:
Your move, Apple. #royalbaby— Mikey Smith (@mikeysmith) September 8, 2014
Still, anything will be better than David Cameron's sarcastic response:
Breaking News, David Cameron choses the worst time to discover sarcasm. pic.twitter.com/mG0msrTthl— Tom Neenan (@TNeenan) September 8, 2014
And Alex Salmond could yet play his trump card:
Alex Salmond: I'm expecting twins.— Deborah Orr (@DeborahJaneOrr) September 8, 2014
But perhaps it's all just a ruse?
What if Kate's only pretending to be pregnant so her keepers bring her more cake? #RoyalPanda— Anya (@anyagrace) September 8, 2014
