“It’s terrifying. Sometimes I just want to post pictures of really stupid stuff but I have such a responsibility. I think that’s why maybe they follow me because with my Twitter no one runs it besides myself. No one tweets for me. No one speaks for me. They see the authenticity, it’s not always me saying, ‘Buy my CD, buy my music…!’ That’s cheesy and desperate.” Katy Perry likes to reach out to her 47.8 million fans directly after becoming the most followed celebrity on Twitter.com. She overtook Justin Bieber, who boasts 47.3 million followers.
