What’s in a name? That’s what we all are trying to figure out when it comes to the interesting choice Bey and Jay chose for their new baby girl. Beyoncé and Jay-Z’s baby girl Blue Ivy Carter arrived Saturday, and while little girls are customarily pretty in pink, this baby is also being surrounded by touches of blue. This was the case over the holidays, when, in anticipation of the baby’s birth, the parents-to-be sent pals blue Christmas gifts, a source tells PEOPLE.
Sources and fans suggest the couple chose the name “Ivy” because of the number 4 or Roman numeral IV, which is significant in Beyoncé and Jay-Z’s relationship.
Beyoncé’s birthday is Sept. 4, while Jay-Z’s is Dec. 4; the two married on April 4 in 2008; they reportedly have matching “IV” tattoos on their wedding fingers; and Beyoncé named her latest album 4.
