“Today we #WITNESS history,” Twitter said Friday in a tweet, referencing the title of Perry 's recently released fifth album. “Congratulations @katyperry, the first to reach 100 million followers! #LoveKaty.”
The 32-year-old singer recently livestreamed her life for 96 hours, inviting fans to watch as she slept, cooked, did yoga, cuddled with her dog Nugget and chatted with a stream of celebrities who showed up at her door.
Despite putting her life temporarily under observation with 41 cameras, Perry -- born Katheryn Hudson to conservative Christian parents in California -- said she struggled to handle the attention to her life more broadly.
