The Beyhive are one of the most clued in fan bases ever, and now they're convinced that Beyonce will be soon to give birth to another little Carter.
Grab out your magnifying glass because we're gonna analyse these clues.
So fans have been posting vids of Bey at her On The Run Tour II concert, and look, her body looks noticeably different to her usual figure.
Take these videos, for example.
The first could potentially just be a bad angle, but the second does show a bit of a bump that looks like it's trying to be hidden with her tassled jacket.
So yeah, maybs a distorted angle on the big screen.
But there aren't many places to hide from this one:
If we needed any further reason to suspect another baby, look at this pic that Beyonce has put on her Insta a few days ago.
The enormous 4.
SURELY this means baby number four.
The Carters also LOVE the number four, so it would make total sense for them to have a fourth child to join Blue Ivy, Rumi and Sir Carter.
I'm gonna hit you with some Four Facts, so see if you knew them already:
1. Bey, Jay and Jay's mother were both born on the 4th
2. The couple were married on the 4/4 (2008. But 4x2=8!)
3. Beyonce and Jay-Z both have albums with the number four in them
4. Blue Ivy was given the name "Ivy" because IV are the Roman Numerals for the number four.
The signs are all there, so it's time for the Carters to let us know!
