Beyonce apparently gave birth eight days ago but has stayed in the hospital with Jay-Z as their twins were born "prematurely" and are being "treated for jaundice"
Rumours have been rife over Beyoncé and Jay-Z's twins - have they been born or haven't they?!
And after Bey's dad Mathew Knowles seemed to confirm the birth on his Twitter account on Sunday, we've all been pretty much convinced that they're here, despite the fact that there's been no official announcement from the Knowles-Carter team.
But there's a reason behind their holding back on the birth announcement.
According to TMZ, the babies were born "prematurely" and are being "treated for jaundice".
The poor family! We can't imagine what they must be going through.
Apparently, the Carter-Knowles duo have been at the hospital for the past eight days, after Beyoncé allegedly gave birth on either the evening of Sunday 11 June, or the morning of Monday 12 June.
Sources told TMZ that the babies were being kept "under the lights" - whilst they wouldn't disclose what they meant by that, babies with jaundice are often kept under "bili lights", a type of light therapy used to treat newborns for jaundice.

According to the NHS, jaundice is common and usually harmless in newborn babies.
It causes their skin and whites of their eyes to become yellow, and can become very serious if left untreated.
Thankfully, that's not the case here!
The NHS website explains that jaundice is caused by "the build-up of bilirubin in the blood", adding that bilirubin "a yellow substance produced when red blood cells are broken down".
Jaundice is common in newborns as young babies have high levels of red blood cells, and their livers are also not fully developed, making them less effective at breaking down the bilirubin.
We hope the babies get better soon - if Beyoncé's pregnancy announcement is anything to go by, we literally cannot wait to see the birth announcement!
