As Halloween parties took over the weekend, Hollywood's finest were out for the festivities.
Singer Fergie and hubby Josh Duhamel attended Kate Hudson's Halloween bash and definitely went all out. The Black Eyed Peas singer dressed up as Elvira, in all her exposed-bosom glory, complete with over the top bouffant wig, thigh-high slit dress, and metallic dagger belt, while Duhamel opted to go for a more ghoulish getup, as Riff Raff from "The Rocky Horror Picture Show". Playing dress-up didn't stop there for the pair -- they also dressed in Day Of The Dead inspired costumes the night before, as seen in an Instagram photo posted by the "Transformer" actor.
Fergie and Duhamel weren't the only ones to join in on the Halloween spirit. Celebrity stylist Rachel Zoe and her husband Rodger Berman also attended Kate Hudson's party dressed up as Sonny and Cher, while supermodel Cindy Crawford and her husband Rande Gerber arrived at a different bash dressed as Slash and Axl Rose of Guns'N'Roses (for more images, click here).
Then there was Julianne Hough, who took her "Orange Is The New Black" costume a little bit too far. And of course, this Halloween wouldn't have been complete without a Miley costume -- thanks Paris Hilton!
And since Halloween hasn't officially happened yet, we're sure to see even more outrageous and over the top costumes (we're looking at you, Heidi Klum!).
