We all know how special the color blue is for Jay-Z and we all know how special the number IV is for B, so of course true fans were not surprised (well maybe a little because, Jay referenced in the track Hello Brookyln, from his critically acclaimed album, American Gangster, that if he ever had a daughter he'd name her Brooklyn Carter) when they learned the name of the Carter's precious princess Blue Ivy, which, pays homage to her dad's favorite color and her mommy's favorite number.  Not to mention Blue was born on the 4th floor of Lenox Hill Hospital in Midtown Manhattan. 

MTV was one of the first sites to remind the mainstream world of the significance of the name and now PEOPLE magazine is doing the same. 



via People Magazine:  Beyoncé and Jay-Z's baby girl Blue Ivy Carter arrived Saturday, and while little girls are customarily pretty in pink, this baby is also being surrounded by touches of blue.

This was the case over the holidays, when, in anticipation of the baby's birth, the parents-to-be sent pals blue Christmas gifts, a source tells PEOPLE.
Sources and fans suggest the couple chose the name "Ivy" because of the number 4 or Roman numeral IV, which is significant in Beyoncé and Jay-Z's relationship.

Beyoncé's birthday is Sept. 4, while Jay-Z's is Dec. 4; the two married on April 4 in 2008; they have matching "IV" tattoos on their wedding fingers; and Beyoncé named her latest album 4.

And the significance of the baby's first name, Blue? Well, Jay-Z has three albums with the word "blueprint" in their titles: The Blueprint was released in 2001; The Blueprint 2: The Gift & The Curse, in 2002; and The Blueprint 3, in 2009.

In lyrics, Jay-Z has rarely been coy about proclaiming himself the best rapper ever. "I'm the Blueprint, I'm like the map for 'em," he said in "A Star Is Born," from The Blueprint 3.

Fans have also chimed in on the name. "Blueprint was the hottest album ever sold by Jay-Z! their child's name makes a lot of sense!" Tweeted @kisssmyDIAMONDS

And Tweeted @omgitsralph: "There's a meaning in Ivy Blue. IVy = a roman numeral for 4 which is Beyoncé's favorite number and BLUE for Jay-Z's Blueprint albums. Wow."

Until then, there's one thing the family is clear about, as proud aunt Solange declared on Twitter on Sunday. Blue Ivy, she said, is "the most beautiful girl in the world."
