Dressing up as someone else is a job description in Hollywood, so it’s no surprise that stars pull out all of their tricks when Oct. 31 rolls around. We’ve rounded up the most creative, clever, and downright outrageous getups from A-list Halloween parties.
Kim Kardashian
Wonder how many guys stopped to stare at this woman.
Pink
We’re not sure if she’s trying to be a sad clown, a gothic Bozo, or a stripper, but if we’d hired her for our party, we’d demand a refund.
Christian Siriano
The designer channels the ultimate diva, Cruella de Vil. Hopefully the PETA protesters took the night off.
Jack Osbourne
It’s great that his uniform at Taco Bell doubles as a Halloween costume.
Mariah Carey
We hope another firefighter is up in a tree rescuing her shirt.
Christina Aguilera and Jordan Bratman
It’s Halloween, not act-out-your-private-bedroom-fantasy night.
Paris Hilton and Three Oompa-Loompas
After wearing an orange jumpsuit (for like a minute) in jail, we don’t blame Paris for changing into a sexier jailbird suit.
Heidi Klum
Catwoman better watch her back. There’s a new sex kitten in town. Meow!
Heidi Klum
When it comes to fashionable Halloween costumes, some years you’re in, and other times you look totally effing insane.
Alexis Bledel, Mena Suvari, and Simone Sestito
No jazz hands needed. This classy trio looks like they’ve just stepped out of a time machine from 1920.
Lo Bosworth
With all the drama on The Hills, maybe Lo should have dressed up as the Big Bad Wolf.
Audrina Patridge
Someone should tell Audrina that Halloween is about dressing up, not just wearing an ugly dress and going crazy with the eye makeup.
