Katy Perry Rules Over Twitter

Katy Perry is the queen of pop and also of social media. The pop singer who stays on the top of the charts just reached 90 million followers on Twitter. That is more than her pop peers Justin Bieber and alleged rival Taylor Swift. Twitter itself congratulated Katy Perry on Monday tweeting out: "It's party time Katy Perry! With 90 million on the guest list, we're gonna need a really big dance floor."
