Lady Gaga is already the reigning queen of Twitter, with her nearly 19 million followers topping those of anyone else on the site. Now, she's launching a site of her own. Little Monsters, now in invite-only beta testing, is the pop princess's effort at creating a network built around her fan base, and will emphasize sharing and creating photos and videos, as well as letting other users promote content from others that they like.
