Halloween is a day to go all out and let your freak flag fly and there is no better place that understands that more than Hollywood. Actors, singers, models, and reality stars know how to go all out on October 31st and this year was no exception.
Miley Cyrus
There is no doubt that this is the year of Miley. Her VMA outfit is the go to for crazy Halloween costume ideas, so why not dress as another infamous VMA outfit. Lil Kim’s purple 1999 outfit is the perfect fit for Miley.

Paris Hilton
Speaking of Miley, Miss Hilton took on the now famous VMA teddy bear one piece and foam finger that shocked the world. As well as adding red shades and the signature tongue hanging out of the mouth, I’ll say the Paris nailed it.

Matt Lauer
Sure womaen can dress all sexy on Halloween, but so can men. Today Show host Matt Lauer proved that point on the Halloween episode of NBC’s Today Show. Donning a blonde wig, red bathing suit, and even the signature slow motion run, Matt captured the pure elegance of Pamela Anderson.

Ellen DeGeneres
Last month singer Nikki Minaj appeared on Ellen dressed very sparingly and bra less. So Ellen decided to dress as what she explains as “something really scary…me half naked.” Ellen had Minaj’s look down pat with pink lipstick, blonde wig, and even fake breasts.

Neil Patrick Harris and David Burtka
NPH and Burtka are always incredibly gifted when it comes to Halloween costumes. Ever since their twin son and daughter arrived it has been nothing but pure adorable. In past years the family dressed as characters from The Wizard of Oz, this year they went for an Alice in Wonderland look. Neil and David as Tweedle Dum and Tweedle Dee are beyond perfect.

Nicole “Snookie” Palizzi and Jenni “JWoww” Farley
After getting the boot from Dancing With the Stars reality star darling Snookie and her bff JWoww for the” Night of the Living Dead” party in NYC. The pair went as the The Queen of Hearts and The White Queen from Alice in Wonderland

Alexa Chung
There is nothing better than a funny costume, and Alexa Chung knows that. The super model and TV host dressed as McDonald’s Hamburgler for a party at NYC’s Refinery 29. Even while dressed as a giant burger she still looks adorable.

Shenae Grimes
The 90210 star took on the sexy Poison Ivy at a party in West Hollywood. Her husband, musician Josh Beech, dressed as Heath Ledger’s Joker from The Dark Night.

Lea Michele
The Glee star showed off her more sexy side as a German Beer Maid. With a short dress, pigtails, and black thigh highs Michele managed to look adorable in the pic she tweeted out in which she poses with a similarly dressed friend.

Fergie and Josh Duhamel
The couple dressed up twice already for Halloween, but the best has to be their homage to Dia De Los Muetros or “Day of the Dead.” Fergie in all black has her face painted like a sugar skull and red flowers wrapped around her hair; Josh is also wearing face paint and a sombrero. Both look creepy and stunning which is a perfect match for the holiday.

Kelly Osborne
The cast of E!’s Fashion Police decided that for their Halloween episode they were going to dress as looks from the past year’s red carpet events. Gulianna Rancic was Sophia Vegara, Joan Rivers was Miley, but nobody captured their star better than Kelly. The host dressed up as the busty Mad Men star Christina Hendricks. Wearing multiple bras and a red wig, she captured the curvaceous actress’ red carpet fashion.

Naya Rivera
The Glee star added a sexy spin to an iconic character. Dressed in a big red coat, giant black hat, and a mysterious briefcase, Naya tackled the looks of cartoon character Carmen Sandiego.

Nicole Richie
In one of the more clever costumes, Richie used her petite size to play Danny Devito. A much taller friend completed the look by wearing matching suits to replicate the look from the movie Twins.

Constance Jablonski
The French fashion model copied the iconic red body suit that Britney Spears wore in her famous “Oops I did it again” video. Constance had the look down pat with the long blonde hair and even a mic piece.

Alessandra Ambrosio
Nobody looked more smoldering than model Ambrosio. The Brazilian born beauty went as the Queen of Hearts to a Hollywood party. She is pretty much knocking all other Queen of Hearts out of the water.
