Best and worst: celebrity Halloween costumes!

Celebrity Halloween costumes are generally pretty good, if only because they have "people" to come up with and create their elaborate costumes.

Case in point, Bette Midler, Heidi Klum, Seal, Kyle McLachlan, and Jack Osbourne, who went as a .... taco.

Check out our favorite 2008 celebrity costumes here:

And "Project Runway" Christian Siriano is probably Cruella de Ville, right? Or just a "hot tranny mess"?
