It's October 31st -- which means it's time to start thinking about your Halloween costume. Here are a few last minute ideas.....

Snooki -- A no brainer. Just orange yourself up!

Katy Perry -- Choose from any of her cute, pin-up girl looks!

Lady Gaga -- Wear a blond wig and make your own "Meat Dress."

French Maid -- An old favorite -- and always a man pleaser.

Anything "Mad Men" -- Just break out the tight pencil skirt (and plan on standing all night!)

Black Widow from Iron Man 2 -- If you can pull off looking like Scarlett Johansson, you can find this costume online.
