Halloween 2025: The Best, the Scariest, and the Most Creative Celebrity Costumes

From Medusa to inflatable mayhem, celebrities pulled out all the stops for Halloween 2025. See which stars delivered jaw-dropping, hilarious, and wildly creative looks.

Halloween 2025 proved once again that when it comes to costumes, celebrities don't just dress up — they go all out. From eerie recreations of historical moments to full-on cinematic transformations, stars turned sidewalks and red carpets into runways of imagination.

Whether drawing laughs, gasps, or straight-up admiration, this year's looks had people talking — and scrolling. One of the most unexpectedly iconic costumes came from former Prime Minister of Canada Justin Trudeau.

The Canadian dressed as a giant inflatable shark mid-attack. His son played the unlucky surfer, complete with a bloody wound and faux fear, as the shark — with a foam surfboard stuck in its jaws — appeared to chomp down mid-bite.

"The nod to left shark is killing me," one netizen wrote. Another chimed in, "Cute! I'm also flashing back to Katy's Super Bowl performance a few years back 😉," referencing the now-viral GIF of Katy Perry's halftime show featuring dancing shark mascots. The internet noticed and approved.

Also winning the internet was Macaulay Culkin, who hit the streets in a giant, inflatable toilet costume — complete with a red cherry on top. His face was painted white and his expression was pure chaos.

"😂😂😂 that's funny [sic]," one fan commented. Another added, "He can't even disguise as a toilet. I knew instantly that was Macaulay Culkin 😂," while someone else noted, "So funny! 😂 Even with face paint, I recognized him right away haha." Clearly, no amount of padding or plumbing could hide that iconic face.

And then there was Heidi Klum — the undisputed queen of Halloween — who turned heads at her 24th annual party in New York with an astonishing Medusa transformation.

Covered in textured, reptilian prosthetics from head to tail, she became a full-bodied Gorgon with writhing snake hair and piercing yellow eyes. Reactions poured in instantly.

"That is absolutely amazing..every year I think it's the best one yet.. but this definitely is...🙌🙌 [sic]," said one fan. Another called the model's costume "absolutely phenomenal work," while a third declared her "THE Queen of Halloween! 🎃 🔥."

However, Trudeau, Culkin, and Klum were just a few of the stars who brought the Halloween heat this year. From campy to couture, the creativity on display was unmatched. Keep scrolling to see the best, the scariest, and the most creative celebrity costumes of Halloween 2025.
