And in true Beyoncé fashion, the singer is keeping us guessing by withholding the sexes and names of her new little ones.
When the couple's first child, daughter Blue Ivy Carter, was born in 2012, they reportedly rented out an entire floor of a NY hospital.
It is not yet clear exactly when the singer was expected to give birth, and how long ago the twins arrived.
Beyonce and Jay Z's twins remained hospitalized a week after their secret birth - reportedly last Monday - for what only were described as "minor issues".
So Beyonce and Jay Z now have a fuller house with Blue Ivy and the new-born twins.
Beyonce looked ready to pop when she celebrated her baby shower with friends and family on Saturday, May 20, at a bash nicknamed The Carter Push Party by her proud mum Tina.
Star has contacted a representative for Beyoncé for comment. There is a new report from the DailyMail claiming that the twin babies will have an incredibly lavish nursery that includes several key amenities.
Reports she had become a mum began swirling this week when rapper Jay Z missed his Songwriters Hall of Fame induction in New York City on Thursday night (15Jun17).
Beyonce announced in February that she was expecting.
She has been silent on social media for the past couple of weeks, fueling speculation that the twins were almost here.
The arrival of the twins was announced by Beyonce's father Mathew Knowles. We have been blessed two times over.
Soon after the bun-in-oven announcement, Bey cancelled her Coachella headlining gig on doctors' orders.
The image took over the internet, becoming the most-liked Instagram pic of all time with 6 million+ views within 24 hours of its posting.
