Beyonce Knowles is crashing a big party called "The Internet" today by launching her very first tweet and an intimate Tumblr site.

"Hey World, It's B! I'm so excited to invite you to my new http://beyonce.com - we've been working hard, and it's finally ready for you XO," she tweeted to 3.5 million fans.

The notoriously private singer rarely gives glimpses into her personal life; now it looks like B has changed her tune. From the looks of her Tumblr account "I Am," Bey is on permanent vacation, hitting the beach with sister Solange, hanging out with her hip-hop husband Jay-Z and posing for endless glamor shots.

"I Am. This is my life, today, over the years - through my eyes. My friends, my travels, my love. This is where I share with you, this will continue to grow as I do," the singer writes on the newly minted site. If you scroll closely you can even find a video of Bey revealing the origin of her baby daughter's name.

When Blue Ivy Carter was born, the music power couple launched an equally intimate Tumblr account, posting photos of the newborn baby in the hospital. Check out a few choice shots from Bey's new site below!
