Celebrity couples' Halloween costumes this year have been quite a treat! From adorable to odd, crazy to creepy, cute to catastrophic, these celebrity couples made some very interesting Halloween twins. Celebrity gay couples led the pack, of course.  Neil Patrick Harris and his husband David Burtka were, as always, completely adorable with an entire-family Alice in Wonderland themed ensemble. Chris Colfer and Will Sherrod geeked out a little with a C-3PO/R2D2 combination - the gay romance we all wanted to see finally a reality. Finally Jesse Tyler Ferguson and hubby Justin Mikita went as the ever camp, ever homoerotic Batman and Robin.

On the straighter side of the street, or more accurately on Kate Hudson's side of the street, celebrity couples made some equally interesting Halloween pairs. Taking us back to some horror movie classics, Fergie went as Morticia and Josh Duhamel went as Rif Raf from "The Rocky Horror Picture Show." Johnny Hallyday and Laeticia Boudou look ghoulish and fabulous respectively. Meanwhile Johnny Knoxville and Naomi Nelson went all out in white. Rachel Zoe and Roger Berman took us back to the past as Sonny and Cher. Finally, Cindy Crawford and Rande Gerber rocked out as the members of Guns 'n Roses.

Celebrities on Halloween certainly know how to rock it. With so many parties to go to and so many costumes to choose from, their is certainly a lot to look for. Some couples though, spent a somewhat sadder Halloween together: Miranda Kerr and Orlando Bloom were photographed together in New York today, however, it was only a brief encounter as the couple recently announced their separation
