Meghan Markle and Prince Harry 's fans are waiting with excitement for any sign that the couple have welcomed their first child.
The parents-to-be are breaking with tradition and keeping the details surrounding the birth secret, which means it's literally just a case of waiting for an official announcement.
But many fans are convinced she'll give birth this weekend - and it's all because of the moon.
A stunning 'Pink Moon' lite up the skies last night , which is also known as the Egg Moon, Sprouting Grass Moon, Growing Moon or Full Fish Moon.
Despite its name the moon actually looked orange, with the term being a Northern Native American reference to an early-blooming wildflower which starts to pop up in the US and Canada at the beginning of spring.
Many believe the start of a full moon, like the one we saw last night, can induce labour.
They believe the full moon's gravitational pull can affect the amniotic fluid which surrounds the baby.
One fan wrote: "Tomorrow is the full moon and also exactly 11 months Harry and Meghan wed in Windsor I think it would be the best day for baby Sussex to present himself into the world."
According to the Royal Museums Greenwich, the full Moon was set to reach its peak little after noon, at 12.12pm, though it would not be easy to see until dusk.

It occurs when the Moon is located on the opposite side of the Earth as the Sun, meaning its face is fully illuminated.
Meghan and Harry revealed they wouldn't be sharing key details earlier this month, a decision which has split fans.
While many agreed with their decision, some are disappointed that they won't be sharing the excitement.
Commentator Carole Malone said she didn't understand why they couldn't "spend two miserly minutes outside the hospital waving and smiling at people who only want to wish them well".
Speaking on Sky News she said: "There we all were looking forward to the arrival of baby Sussex and boom Meghan and Harry make the announcement that there will no announcement.

"Someone needs to explain to me how a statement announcing the baby’s name, weight and gender, would invade their privacy or deny them precious family time.
"This is an unprecedented slap in the face for those legions of decent ordinary people who love the Royal Family and who see the Royal birth as a joyous, national celebration.
"No one is expecting Meghan to parade her baby minutes after giving birth, and, of course, they’re entitled to private time with the Baby Sussex.
"But how hard would it be to spend two miserly minutes outside the hospital waving and smiling at people who only want to wish them well?
"Us Brits give so much to the Royal Family, and we also pay for the privilege of having them. Isn’t it time the Royals gave something back?"
