Baby, I paint the sky blue
Blue is the name of his and Beyoncé’s daughter, supposedly named so because of the success of The Blueprint and the subsequent albums (and here I was sure his daughter would be named Brooklyn Carter…)
Her middle name is Ivy, due to Beyoncé’s love for the number 4 (Ivy = IV, Roman numerals for four). She acknowledges it as a number that is special to her because among other things her and Jay’s birthdays both fall on a 4th, they were married on the 4th, etc.
It should be noted that the Empire State Building was all blue the night Blue Ivy was born
