Beyonce and Jay-Z welcomed their first child Saturday night at New York’s Lenox Hill Hospital. The baby girl, named Blue Ivy Carter, has had the attention of media and fans since her mother dramatically announced her pregnancy at the Video Music Awards last fall.

Speculations surfaced about everything from the baby’s due date to a future career in music, according to The Reliable Source:

The first child for hip-hop’s royal couple, who wed in April 2008, has been the most anticipated and rumor-generating celebaby of the year (unless Kate Middleton steps up to the plate). 

The name chosen by the proud parents has already sparked a few conspiracy theories, and some strong opinions. One such rumor suggests that the name Blue Ivy proves that the couple are members of the Illuminati, reports Jen Chaney of Celebritology:

There are other online theories floating around that seem flat-out ridiculous, including some that purport that the innocent girl’s name actually means Lucifer’s daughter when spelled backwards. (It doesn’t.)

A more legitimate explanation for the name comes courtesy of People and other outlets, which points out that “Blue” may be a reference to Jay-Z’s “Blueprint ” albums, and Ivy may be a riff on the number four, a lucky one for Beyonce and her husband. (IV is, of course, the roman numeral four.)

There are plenty of other explanations for the slightly abnormal name choice, though the couple has not made an announcement about the child’s birth or her name.

Despite the speculation, Janice D’Arcy of On Parenting noted that a generic name might not be fitting for a child who will inevitably spend a lot of time in the spotlight.

Another explanation may be that Blue Ivy’s parents knew that there was no reason to follow rules like the level-headed advice Jennifer Griffin gives in her new baby-naming book, “Bring Back Beatrice!” (Workman Publishing, 2011):

“Give him a name that will work in any situation, and if he wants a cooler name for show business, he’ll change it himself.”

Little Blue Ivy will never, even when her tendrils grow into adulthood, be obscure. Why give her a name that suggests otherwise?

Besides, is pairing two rather pretty words together make a name so wrong?
