Beyoncé and Jay-Z married on April 4, 2008, in a famously private ceremony in New York. This countdown runs to the next 4/4.
Both were born on the 4th (September 4 and December 4), they married on 4/4, both have 'IV' tattoos, and the number echoes through their work — her album 4 and his 4:44. Music's most famous couple kept the wedding so private that no photos were released.
