4. Four. Nuff said.
History has shown us time and time again that 4 is the Carters' magic number. It’s tatted on Jay and Bey’s fingers, it’s the title of her 2008 album, their birth dates are the 4th and they wed on the fourth day of the fourth month. Heck, Blue’s middle name is rumored to be conceived from the roman numerals for four (IV and Ivy, get it?). Why not round out the family roster to complete the pattern?
