15 Shocking things you didn’t know about Beyonce & Jay Z’s relationship (With Pictures)

5. Four Is Their Favorite Number

Given that both of the stars were born on the 4th of the month, (Beyoncé’s birthday is in September and Hov’s is in December), both of stars favor the number 4. In addition to that, each of the stars seems to be intrigued by astrology and use it as a method of spiritual guidance, which had only deepened their bond over the years. This is also the reason why they named their daughter Ivy as IV is the Roman numeral symbol for 4. However, we’d be remiss if we didn’t point out that naming the child Blue raised a few eyebrows due to Jay Z’s rumored list of cheating conquests.
