It's officiall, Bey is a mommy!  Congratulations to the Carter's who welcomed their brand new baby girl, Blue Ivy Carter late Saturday night!  E! Online reports that multiple sources have confirmed that the couple welcomed their first child Saturday night.
Reps for the couple haven't given the official word on their bundle of joy, but there's no dening this little girl is here because her famous friends are already welcoming her by way of Twitter.  Sending their love are the likes of Rihanna to Russull Simmons to Gwenith Paltrow.  So, it's pretty much a done deal that she's arrived.
According to New York Daily News, Beyonce reserved the entire fourth floor of the hospital for ruffly $1.3 million to make sure that her baby's entrance into the world was closely guarded.
Speculation that Queen B's due date was nearing was intensified right before New Year's Eve, as Beyonce's mother Tina, sister Solange and her family arrived in New York -- no doubt to welcome their newest family member.
This is the first child for the first couple of Hip-Hop, who married in April 2008.
