Four is her favorite number.
Beyoncé and Jay-Z's birthdays both fall on the fourth day of their respective months.
In fact, she loves the number so much she and her husband, Jay-Z, have the Roman numeral of it, IV, tattooed on their ring fingers.
Some fans have suggested the Roman numeral, which stands for four, inspired the second part of the couple's daughter's name, Blue Ivy.
The name Ivy is pronounced the same way the letters "I" and "V" would be.
