According to US Weekly, their baby - which is due in February - will have a whopping 2,200 square foot nursery!
An 'insider' told the mag that the couple are already getting their New York Tribeca apartment ready for the patter of tiny feet and claims that the baby room will be off the scale size wise
The source goes on to say though that not all Beyonce's and Jay-Z's friends are convinced by their mega-crib idea, claiming that some pals have said 'won't you be scared to leave your baby in that huge room?'
We can only imagine that if Mariah Carey ($1million nursery) and Posh Spice (£10,00 Harrods baby furniture spree) have heard this news, they are drawing up plans for an extension Right Now.
Would you go all out and have a mega-nursery is space and finances allowed?
Or is a small, cozy room more important for a newborn?
