For most of her solo career, Beyoncé has been like the Diana Ross of her generation: a glamorous diva who's wowed us with her prodigious talent and envelope-pushing style while maintaining an arm's-length distance that gave her a pop royalty air.

But on Thursday (April 5), she joined the Lady Gagas and Katy Perrys of the world by taking a dive into the social media pool. For fans of a singer so private she wouldn't even confirm her marriage to hubby Jay-Z for years, it was a precious peek into the glamorous, globetrotting world of music royalty.

The "Love on Top" star announced the foray with her first tweet, "Hey World, it's B! I'm so excited to invite you to my new beyonce.com -- we've been working hard, and it's finally ready for you XO." (It's worth noting that at press time with only one tweet, B's account already had more than 3.5 million followers.)

And when fans checked into the personal Tumblr she'd set up, well, their dreams were answered. The page is a treasure trove of private moments, from Queen B chilling on exotic vacations with sister Solange, to pics of her arm-in-arm with Jigga, silly Halloween shots, pregnancy photos, arty still lifes and even a 15-second video in which a visibly pregnant Bey walks by a blue ivy tree.

Of course, daughter Blue Ivy was born earlier this year and people have been scrambling to figure out the meaning of the name for months.

The site also has a number of shots of the singer's nephew, Julez, and in a message entitled, "I Am," she explains, "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. Love, Beyonce."
