Katy Perry and Taylor Swift are bitter rivals, and it looks like Katy just got a leg up on Taylor that we can't imagine the "Bad Blood" singer will be happy with! It was just announced that Katy is the most popular person on Twitter - she beat out Justin Bieber too!
Katy is the first person to reach 80 million followers on Twitter, while Taylor is still sitting at 68.9 million and Justin has 72.9 million.
Katy recently said about her Tweets, and why fans love them so much, "I would say 90 per cent of my Tweets, I've just made them up and you can tell because many of them are misspelled and full of typos. But the other five per cent is work related or it's just to keep people in the know about where I'm playing or if I'm doing a show and I always get really confused."
Taylor doesn't like to not be number 1, so we have a feeling she will soon launch a campaign to get her more Twitter followers!
