Lady Gaga launches social site

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.
