America's media-shy sweetheart Beyonce has always held the internet at arm's length, but to celebrate the fourth anniversary of her wedding to Jay-Z, she's launched a personal Tumblr and tweeted her first-ever tweet. Similar to the page she and Jay created to celebrate the first pictures of their daughter Blue Ivy, the site shares a stream of candids. Beyonce promises to keep the space active, saying, "This is my life, today, over the years—through my eyes. My family, my travels, my love. This is where I share with you. This will continue to grow as I do."
