The singer, who released her fifth studio album Witness this month, has frequently used Twitter throughout her career to announce new singles, tours, and sometimes, to air grievances. (Regarding grievances: Perry’s noted rival Taylor Swift has a comparatively paltry 85.1 million followers.)
Coincidentally, Perry hit her milestone the same morning President Trump tweeted about having “over 100 million people” following him. (In truth, he has merely 32.4 million Twitter followers, and only cracks 63 million when adding in his Facebook and Instagram followings.)
To honor the Katy Perry milestone, Twitter released a custom emoji.
