It’s been two and a half weeks since the world learned that Kate Middleton and Prince William are expecting royal baby number three, and the hype has yet to settle down.

There’s been discussion about whether Prince George and Princess Charlotte will be welcoming a brother or sister, conversation about baby names and, of course, speculation about when exactly the 35-year-old is due.

And thanks to a massive hint dropped by Prince William this week, we may be one step closer to solving that mystery.

(Yes, that means eager royal watchers can start making plans for camping out in front of London hospitals.)

It's long been thought that Kate and co. waited until she was at the end of her first trimester, the 12 week mark, before going public with the pregnancy news.

According to calculations, this meant Royal Baby Number Three would make his or her debut in April 2018.

But this week, William joked with a midwife that he may be seeing her "sooner than you think".

Sooner than you think, you guys.

The Prince's words have some believing that Kate was well past her first trimester when the news was revealed and that another royal baby could be in our presence as soon as March.
