From Cheeto to Clinton — Katy Perry’s best Halloween costumes as new relationship goes public

David BenjaminOctober 30, 2025

A compilation image of Justin Trudeau and Katy Perry at red carpet events — Spooky season is undoubtedly the favourite time of year for celebs. Every October, our Instagram timelines are littered with Halloween costumes — some raunchy, some impossibly scary — but always a 10/10 on the effort scale. While Heidi Klum is indisputably the ‘weeny Queen (erm, the worm, everyone!), Katy Perry has also pulled off some iconic looks over the years. And, considering she’s the centre of attention right now thanks to going public with her new beau — who is none other than former Canadian Prime Minister Justin Trudeau — all eyes are on the Dark Horse singer this month to step out in something more legendary than ever. So, as inspiration for this weekend’s festivities, let’s take a look at some of Katy’s most epic Halloween outfits over the years. Plus, some of pop culture’s other impeccable celebrity fits.

Five years earlier, she turned up to Kate Hudson’s annual Halloween party dressed as a human Cheeto — a look that Katherine Ryan would later take inspiration from in 2023 when she dressed up as a giant wotsit. In 2024, Katherine took her snack-themed costumes to new heights when she transformed into a massive Monster Munch, but that’s a different celeb and different story for another day.
