In celebration of their fourth wedding anniversary, Beyonce has decided to release over 150 personal photos of herself and rap superstar Jay Z on her new Tumblr blog.

The photos will detail the ten year relationship of music's power couple and will include numerous trips, loving moments and a few personal shots.

Given that both have kept their relationship pretty private over the years, the fact that this is their fourth anniversary and Beyonce "loves" the number 4 could play a role into this decision.
