Royal baby mania is afoot - in fact, we've sent roving reporters down to the Lindo Wing RIGHT NOW to see fans gathering outside. You see, Prince William has taken paternity leave, meaning the baby is ALMOST ON THE WAY.
Naturally, a new royal baby means lots of predictions about what the little tyke, boy, or girl, will be called. We even made a royal baby name generator so you could have a guess yourself.
One thing's for sure though, if it's a girl, she won't be called Charlotte.
Top historian Clarissa Campbell Orr from Anglia Ruskin University (her specialist subject: the British monarchy), has told Royal-loving paper The Daily Express that Charlotte is DEFINITELY out. So don't place your bets on a little Lottie making her way out of K-Middy's womb this month.
Why? Because previous royal figures with the same name have had a bit of bad luck.
She revealed: "There is a popular tide of opinion hoping that if it is a daughter she will be named Charlotte. However, from the point of view of the Royal Family, this is unlikely to be a particularly favourable name.
"George III's wife, Sophie Charlotte of Mecklenburg-Strelitz, was a very successful consort and weathered the disturbing episode of her husband's apparent madness, although her hair turned white with shock."
Another royal, George III's daughter, was called Charlotte, and she was also deemed a disappointment "after she married a Duke of Württemberg in Germany against their will".
Then there was Charlotte, the Princess of Wales, who was grand-daughter of George III. She was hugely popular, the Princess Diana of her day - but tragically died of post-partum haemorrhage after giving birth to a still-born boy.
Since then, Clarissa said, "no monarch has christened a daughter Charlotte and I doubt it would be even a second name because of its unhappy connotations.”
Her prediction that hasn't stopped the odds at Charlotte being chosen staying at 40/1. Alice, Elizabeth and Diana are also hotly tipped to be chosen.
James currently stands as the favourite if the baby is boy.
