Beyonce's baby Blue Ivy Carter gets a song from her daddy Jay-Z Blue Ivy Carter, Beyonce and Jay-Z's much-anticipated baby girl, arrived over the weekend and is already making major headlines. Monday morning saw the release of "Glory," a tribute track from Jay wherein he reveals an excessively adorable amount of excitement over his firstborn -- and that Beyonce suffered a miscarriage before Blue was conceived. "Last time the miscarriage was so tragic / We was afraid you'd disappear but naw / Baby, you magic," Jay says on the track. The musician born Shawn Carter also mentions "false alarms and false starts / all made better by the sound of your heart." Now that Blue is here, all is well -- and delivered naturally, despite rumors of a C-section. A small sample of her crying appears on "Glory," which we totally qualify as her musical debut. So we should get used to her name, one that's generated much social media commentary and analysis. The color blue is heavily associated with Jay's career -- from his trademark blue fitted Yankee cap to his earlier series of smash records, "The Blueprint." Ivy, suggests the New York Daily News, is taken from "IV," the Roman numeral representing the number 4. Bey and Jay have long been obsessed with the number, as both were born on the 4th and got married on that date. Beyoncé's latest solo LP, her fourth, was titled "4." We think you're getting the picture. Now, in grand tradition for this chart-topping pair, the good news is always sprinkled with a bit of drama. One other new parent alleged that access to his child was limited because of the security surrounding Blue and her visitors. "People don't need to be treated like this when dealing with sick children," the angry father told a New York CBS affiliate. He alleged that a hallway giving access to the neonatal intensive care unit, which is reserved for care of premature babies, had been closed to accommodate the star party. Lenox Hill is denying this. "No security plan that we or the Carters' security team put in place would have prevented or delayed families from gaining access ... and to date, no families have complained to the hospital about being denied access to the NICU," the hospital said in a statement. Then there's the case of Beyonce's former Destiny's Child bandmate Michelle Williams, who decided to deliver her congratulations in a form other than Twitter. And that didn't go over well. After badgering messages from fans who demanded she praise Bey and Blue, Williams struck back by explaining her warm wishes would be made in person. I do NOT have to say congrats to someone when they're NOT on twitter...ESPECIALLY when I talk or email them all the time....or when I'll be physically present as well...so [sic] harrassing and stalking my timeline to see if I've mentioned something is POINTLESS!!! My friendship with people aren't always for twitter display," Williams wrote. Beyonce has a baby girl!
