E! News is reporting that Beyoncé and hubby Jay-Z have welcomed into the world their first child together. After many weeks of rumor and speculation over whether or not Bey gave birth or not, E! is reporting today that she has — in fact — given birth. As you may recall, we saw photos yesterday of Beyoncé out and about in NYC still very much pregnant … but at some point last night, it is being reported, she gave birth to a baby girl by C-section. Click below for all the reported deets of the birth of baby B-Jay … including the little girl’s name.

Beyoncé and Jay-Z welcomed a daughter Saturday night in New York, the little one’s arrival coming via scheduled C-section, multiple sources confirm to E! News. And the pop ‘n’ hip-hop princess’ name? Drumroll, please … Blue Ivy Carter! (At least that’s what Jay-Z is telling pals at this point—the couple’s reps have not immediately responded to calls seeking comment.) Friend and music mogul Russell Simmons was among the first to celebrate the arrival, tweeting the new parents: “congrats to my good friends Beyonce and Jay-Z.” Rihanna gave baby Blue a warm welcome, tweeting: “Welcome to the world princess Carter! Love Aunty Rih.” … Beyoncé memorably revealed that she was pregnant onstage at the MTV Video Music Awards in August.

Unlike the previous rumors, this report from E! News seems to be the real deal. The fact that celebrity friends like Russell Simmons and Rihanna are tweeting their congratulations seems to be the most telling thing about the verity of this report. There seems to be conflicting reports about the baby’s name tho … E! says her name is Blue Ivy after they originally reported it was Ivy Blue, others maintain her name is Ivy Lewis — at this point, without official confirmation, we can’t be sure … but whatever baby girl B-Jay is named, I think it’s pretty safe to assume that she has, indeed, been born. Still, the name Blue Ivy has people speculating that the name might be a veiled reference to a new Jay-Z album titled The Blueprint IV. HMMMM. The New York Daily News has the reported deets of the strict hospital security measures set in place for Ivy Blue‘s birth:

A very pregnant Beyoncé had checked into the upper East Side hospital on Friday night under the name “Ingrid Jackson,” a hospital staffer told the Daily News. Beyoncé and her hip-hop hubby, whose real name is Shawn Carter, rented out the hospital’s entire fourth floor for $1.3 million, the employee said. On Saturday night, people were seen bringing bags of takeout and a dozen bottles of red wine onto the heavily guarded hospital wing. After 11 p.m., even doctors and nurses were barred from entering the fourth floor, prompting one doc to complain that he had patients to see. In an effort to keep images from leaking to the public, hospital workers placed tape over security cameras and are forcing employees to turn in cell phones when they arrive for their shifts, a source said. Several security guards were spotted patrolling the perimeter of the hospital Saturday night. A Lenox Hill staffer confirmed that a patient named Ingrid Jackson was in a “labor room.” Reps for the power couple did not return requests for comment.

LOL! All I can say is, that shit cray. Let’s send out love and congrats to the entire Knowles-Carter family. I wonder how long it’ll be before we get our first look at Beyoncé‘s baby girl.
