Why Beyonce, Jay-Z Named Baby 'Blue Ivy' Plus: drama as bodyguards block new dad from premature twins By Evann Gastaldo, Newser Staff Posted Jan 9, 2012 9:39 AM CST Updated Jan 14, 2012 12:08 PM CST 19 comments Comments Beyonce Knowles, right, looks at Jay-Z during the men's championship match between Novak Djokovic of Serbia and Rafael Nadal of Spain at the U.S. Open tennis tournament in New York, Sept. 12, 2011. (AP Photo/Charles Krupa) (Newser) – Beyonce's baby entered the world this week to great fanfare, and yes, her name really is Blue Ivy, not Ivy Blue as was initially reported. If you don't believe us, ask Gwyneth Paltrow: After initially tweeting, "Welcome to the world Blue! We love you already," Paltrow cleared up the confusion by adding, "It's Blue Ivy Carter!" Why did they name her that? People reports that "Blue" may have something to do with Jay-Z's three Blueprint albums (sample self-congratulatory lyric: "I'm the Blueprint, I'm like the map for 'em."). As for Ivy, sources say it has to do with the Roman numeral for four, IV, a significant number for Beyoncé and Jay-Z. They were both born on the fourth of a month, they married on the fourth of another month, they have matching "IV" tattoos, and Beyonce's most recent album was named 4. More from the world of Babyoncé: Not even two days old yet, and Blue Ivy is already causing drama: Thanks to the small army of bodyguards making sure proud parents Beyoncé and Jay-Z were safe at Lenox Hill Hospital yesterday, another new dad says he was kept from his premature twins. "Three times they stopped me from entering or exiting the NICU (Neo-natal Intensive Care Unit) and it happened once on Friday just because they wanted to use the hallway," Neil Coulon tells the New York Daily News, adding that in one instance he was barred for 20 minutes by private security, and that his relatives were kicked out of the waiting room by bodyguards. Anonymous staffers note that Bey and Jay spent $1.3 million to not only seal off, but redecorate, an entire wing of the hospital. Coulon isn't the only one being inconvenienced by Blue Ivy's birth: A Boston event planning company named Blue Ivy has been getting tons of calls, texts, and Facebook messages since the birth, TMZ reports.
