Singer Katy Perry, who just released her electronica-inflected album Witness, has become the first Twitter user to reach 100 million followers.
Perry joined Twitter in February 2009, reaching 50 million followers on @katyperry by mid-2012.
The second most-followed Twitter account belongs to Justin Bieber, who currently has 96.7 million followers.
Next in line are Barack Obama (90.8 million), Taylor Swift (85.1 million) and Rihanna (74.1 million).
Twitter congratulated Perry on reaching the milestone with a retrospective video of her tweets over the years.
However, Twitter is known to be plagued by many fake accounts. According to Twitteraudit.com, about 62 million of Perry's followers might not be real.
She's also set new records on YouTube, with the video for single 'Bon Appetit' topping 16.8 million views in 24 hours after it was released last month (breaking her own record, previously set with 'Roar').
Her Witness tour in the US and Canada kicks off on September 9 and runs through February 2018.
In addition, Perry recently landed a gig as a judge on ABC's reboot of American Idol, and this week helped announce the audition schedule for the show.
