Beyoncé and Jay-Z will launch a Tumblr page to celebrate their four-year anniversary.

Reports say that hip-hop's first couple, who tied the knot in a private ceremony on 4 April, 2008, intend to give fans a peek into their personal life through the site.

The notoriously tight-lipped singer and her music mogul hubby are believed to want to use the account to share intimate snaps of their life throughout their four years of marriage.

Queen Bee, 30, and Jay-Z, 42, whose relationship spans at least a decade, also plan to send out wedding pictures, pictures of them kissing and family moments.

It is no secret that the number 4 holds sentimental value for the power couple and they say it is their lucky number.

The number is the name of Beyoncé's platinum-selling album and represents the birthday of her and Jay-Z. And they got married on the fourth day of the fourth month.

Here are just a few candid snaps sent out to fans:
