In honor of Beyonce and Jay-Z's fourth wedding anniversary, the "Run the World" singer, 30, released hundreds of intimate family photos on her Tumblr Wednesday.

Among the moments shared?

A video of a pregnant Beyonce on vacation in Croatia last September, showing off her baby bump in a ruffled, white two-piece, and talking to an off-camera Jay-Z about a serendipitous discovery on their morning stroll.

"We woke up this morning, took a nice little walk, passed by this beautiful blue tree," Beyonce shares, pointing out the unusual-hued plant covering the tree's bark. "I think it's Blue Ivy, which would be quite appropriate!"

The chanteuse and her rapper hubby's first child, Blue Ivy, was born a little over four months later on January 7.

This isn't the first time Beyonce has let fans get a glimpse of her life behind the scenes. The Grammy winner took to her Tumblr in February to share sweet photos of her and Jay-Z's beautiful daughter with the world.

Blue Ivy's mama also tweeted for the first time Thursday. "Hey world, it's B!" she wrote to her nearly 3.6 million followers. "I'm so excited to invite you to my new've been working hard and it's finally ready for you XO."
