Some big celebrity Halloween parties went down last night all around the country -- and we've got all the scary, sexy and over-the-top costumes.
Dia de los Muertos was a big theme on Friday in NYC, where Bette Midler hosted a Day of the Dead-themed bash attended by Debra Messing, Stevie Wonder and John McEnroe.
In L.A., Paris Hilton looked cute in a She-Ra costume, sister Nicky was a cat and David Arquette made a convincing pimp.
AnnaLynne McCord went BIG in Las Vegas, where she and sisters Rachel and Angel dressed in some Marie Antoinette costumes.
"Jersey Shore" star Jwoww also parties in Sin City, where she (naturally) wore an outfit that showed off her biggest assets.
Check out all the costumes above!
