Perpetual rumor has turned into enthralling reality:

Kate MIDDLETON IS PREGNANT WITH HER THIRD CHILD!

No, really: KATE MIDDLETON IS PREGNANT WITH HER THIRD CHILD!

You've likely read that sentence so many times in the past that you started to doubt whether it would ever be legitimate.

But it wasn't a supermarket tabloid making the gigantic announcement on Monday morning... it was Kensington Palace!

“Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child,” the statement read, referring to Kate and Prince William and adding:

"The Queen and members of both families are delighted with the news."

Middleton once again is suffering from a condition that causes severe morning sickness, just as she did during her first two pregnancies.

As a result, she approved the reveal of this news early (Middleton is not even three months along) and was forced to cancel an appearance in England on Monday.

Explains The Palace:

“As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum.

"Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today.

"The Duchess is being cared for at Kensington Palace."

We can't say for certain when Middleton or William will speak on the pregnancy themselves, but Prince Harry has officially become the first family member to do so.

"Fantastic, great, very, very happy for them," Harry said in a video shared by The Daily Express' royal correspondent several hours ago.

When asked how Kate is doing, Prince Harry responded as follows:

"I haven't seen her for a while but I think she's okay."

(Editor's Question: How long until we also learn that Pippa Middleton is pregnant? Or Meghan Markle is pregnant?)

A Clarence House spokesman, meanwhile, has said that Prince Charles and Camilla are "delighted" with the news.

Kate and William are already parents to a precious four-year old named George and an adorable two-year old named Charlotte.

Despite the young ages of these children, fans have been wondering for months and months just when Middleton would get pregnant again.

The impending birth will relegate Prince Harry down to sixth in line to the throne.

But he doesn't seem too bothered over that fact, does he?

At this point, we do not know when Kate is due or whether she'll have a boy or girl.

We don't know whether the beloved couple will even find out the gender ahead of time or not.

And we definitely do not know the names Middleton and William are considering.

But do you have any suggestions? What about Clarence for a boy and Roxanne for a girl?
