Katy Perry's cake 'poison theory' has sent social media into a frenzy after the pop star's 40th birthday celebration turned into an unexpected viral moment. A video shared by Page Six shows Perry throwing a large birthday cake backstage during her Lifetimes Tour on 25 October 2025, only for it to splatter across the floor, and for her dancers to eat it moments later.
The clip has gained more than 3 million views across TikTok and X (formerly Twitter), sparking debate over whether the incident was a bit of harmless fun or a tone-deaf display of celebrity indulgence. The custom-made cake, reportedly worth £350 ($430), was prepared by Perry's team as part of a backstage surprise.
