Jay-Z stopped by Jacob & Co. jewelers in NYC this afternoon. He had a smile on his face as he stepped inside and chatted with owner Jacob Arabo on his way out of the store. Today is Jay-Z's fourth wedding anniversary, and he and wife Beyoncé Knowles apparently plan to celebrate with their fans. Jay-Z and Beyoncé are releasing personal pictures from their almost 10-year relationship on a new Tumblr account that was created in Beyoncé's name. The images have yet to be shared, but in the meantime, we've rounded up some of Beyoncé and Jay-Z's cutest moments, which include the first snaps of their baby daughter, Blue Ivy.
