Katy Perry is the most popular person on Twitter.
The 'Roar' hitmaker became the undisputed queen of the social network over the weekend, knocking teen idol Justin Bieber off the top spot when her followers crept up to 46.54 million, compared to Justin's 46.51 million.
Katy also has the edge over the 19-year-old 'Baby' singer on Facebook, boasting 59.26 million friends to Bieber's 57.28 million.
Justin originally took the crown from Katy's chart rival Lady GaGa in January. The 'Applause' singer, whose current Twitter tally stands at 40.40 million, had previously held top position for two years.
According to website twittercounter.com, US President Barack Obama and country singer Taylor Swift round out the top five of the most followed people on the social media site.
Katy credits her popularity online with staying positive and ignoring her haters.
She previously said: ''I don't know they exist because I don't give them attention. If you tried to please everyone, you'd have no sense of self. You'd lose yourself in the process of being a people-pleaser and there'd be nothing unique left.''
The 28-year-old pop star also revealed her biggest tip is to never drink and tweet.
She joked: ''When you decide to have a glass of wine, put the phone down. Don't drink and tweet.''
