Superstar couple announced the birth of their little Blue Ivy in January 2012 after a long anticipated pregnancy. Wait, what? Blue Ivy Carter? (Jay-Z’s real name is Shawn Carter). But why Blue Ivy? Another off-beat celebrity name. It’s almost like they’re trying to out-do each other at this point. It’s unclear why the couple chose Blue Ivy, but it’s been speculated that Blue is Jay-K’s fav color and Ivy is representative of IV (Roman numeral for the number 4). Both Beyoncé and Mr. Carter have birthdays on the fourth day of the month and their anniversary date is April 4.
