Beyonce checked into Lenox Hill Hospital in Manhattan with husband Jay-Z on Friday. Last night Queen B herself brought baby girl Blue Ivy Carter into the world. ‘Ivy’ stands for the significance of the number 4 in the couple’s relationship; both Beyonce and Jay-Z were born on the fourth — Sept. 4 and Dec. 4. They were also married on April 4, 2008, and Beyonce’s latest album is ‘4’. Beyonce checked into Lenox Hill Hospital in Manhattan with husband Jay-Z on Friday. Apparently the couple had rented out the hospital’s entire fourth floor, paying 1.3 million dollars for privacy. I’m sure she was worth the investment. Congratulations Bey and Jay, and welcome to the world Blue Ivy Carter!!!!
