It’s official: Chris Brown is the worst person ever. While most of us knew that he wasn’t the most picture-perfect celebrity in the world, his Halloween costume this year definitely put any doubts we had about that statement right out the window.

Instead of dressing up as your typical ghost, goblin or fellow celeb, Chris decided to go down a different route and dress as an Arab terrorist with a group of friends. Yup, SO hilarious Chris (insert heavy sarcasm).

Hope you had a great Halloween, everyone! Getting their start last weekend, celebrities have been jumping at the chance to show up to the best parties in their craziest costumes and they seriously delievered!

Since people always take things to the next level in Tinseltown, we’ve rounded up some of the best and most outrageous costumes stars wore out on the town last weekend and on the big night itself. And if you need a costume idea for next year, you can always take a cue from these celebs!

Check out the costumes from Kim Kardashian, Pretty Little Liars, Jessica Alba and more after the jump!

When is a wardrobe malfunction not a wardrobe malfunction? On Halloween, of course.

Ellen DeGeneres was looking particularly curvy on her show yesterday, and baring a little more ass than usual, too. But that’s because her costume was Sofia Vergara’s Emmys wardrobe malfunction!

Watch the hilarious gag after the jump!
