Saturday brought a highly-anticipated arrival to the celebrity baby world--the superstar couple Beyoncé Knowles and Jay-Z welcomed their daughter at Lenox Hill Hospital on the Upper East Side of Manhattan. The arrival was more than a month before the couple's previously revealed due date, PEOPLE.com reported. The baby and mother are both reportedly doing well.
Inspired by nature, Ivy is an old-fashioned name that's starting to make a comeback after a century-long nap. US Weekly reports that the couple chose "Ivy" because of the significance of the number "4"³ or "IV," in their lives. Beyoncé and Jay-Z were born on Sept. 4 and Dec. 4, respectively, were married on April 4, 2008, and Beyoncé's latest album is entitled 4.
Both the names Blue and Ivy may have musical antecedents. A film about jazz singer Billie Holiday's life was called Lady Sings the Blues and another early jazz singer was Ivy Anderson.
