Too complicated to explain on the air.... so you can read how Beyonce and husband Jay-Z came up with their little girl's name!
For Jay-Z and Beyonce, the name Blue Ivy is music to their ears.
The superstar parents have a long association with both parts of their baby daughter’s moniker.
Jay-Z's seminal 2001 album was titled "The Blueprint," and it became the first in a trilogy, with two more Blueprint records in 2002 and 2009.
"My favorite hue is Jay-Z Blue," he rhymed on Young Jeezy's “Go Crazy” in 2005.
"Blue Magic" was the first single on his 2007 album "American Gangster," and a massive blue-tinted billboard featuring Jay-Z and his Nets basketball team co-owner Mikhail Prokhorov towered on Eighth Ave. near Madison Square Garden this summer — ahead of the New Jersey team's move to Brooklyn — along with the title "the blueprint for greatness."
Ivy, meanwhile, is rumored to be a play on IV, the Roman numeral for the power couple's beloved number four.
Beyonce's latest studio album was titled "4" — and not just because it was her fourth solo album, she told Billboard in May.
"We all have special numbers in our lives, and four is that for me. It's the day I was born, my mother's birthday, and a lot of my friends' birthdays are on the fourth. April 4 is my wedding date," she said.
Jay-Z, meanwhile, was born on Dec. 4, 1969.
The rap mogul, whose real name is Shawn Carter, even has the digit in the name of his popular Manhattan sports bar — the 40/40 Club.
Twitter claims that the baby name has a dark biblical meaning when spelled backwards have been debunked.
While there's still no official word on the moniker from the new parents, it has garnered mixed reaction from the public.
An Us Weekly poll this weekend reported that 78% of readers didn't care for it.
