Here is Twitter's reigning queen.

Katy Perry just passed the 50 million followers mark on the social network. Okay, you'd be right pointing out this isn't the most important of news, but hey, it's a milestone for one of the biggest social media companies in the world. Now, 50 million really is a huge amount. If there's one "secret" to her Twitter success, it's that she's personally active on it. She tweets her own pictures and comments on things frequently, instead of relying on a bunch of retweets and robot-like advertisements in her posts. Perry is 800,000 followers ahead of the next most-followed person: Justin Bieber. If there's one less thing Bieber hasn't gotten a hold of, that's a win in our book.
