One Direction, Kanye West, JWoww: Which Celeb Rocked The Best Halloween Get-Up?

1D's Liam Payne, Kim Kardashian, Diddy, Emma Roberts get in the spirit with clever costumes.

With Hurricane Sandy gearing up to wreck havoc in the Northeast, that didn't stop celebrities from missing out on the Halloween fun. Everyone from Kim Kardashian to Emma Roberts opted for their sexiest, or their scariest, Halloween costumes this past weekend.

Kim Kardashian got aquatic this Halloween weekend, transforming into Darryl Hannah's mermaid look from the flick, "Splash," sporting a long, blond wig and a seashell top. Yet, to complete her costume, Kardashian had Kanye West as her "captain." Kardashian tweeted a photo of the two of them together, writing "Me & my captain," before the two attended the 2nd Annual Midori Green Halloween Party in New York.

A host of other star-studded couples got into the early Halloween spirit, including Ryan Seacrest, who shared a photo of himself and girlfriend Julianne Hough, with the caption "Bonnie, Clyde, and the jail yard dogs."

Fergie and husband Josh Duhamel got creative with their Halloween costumes, dressing up famous self-promoting actors Angelyne and Dennis Woodruff.

"The Voice" coach Christina Aguilera, took the sexy route this Halloween. The "Your Body" singer sported a revealing fish-net look with a large pink wig and white crown, while her boyfriend Matthew Rutler was her knight in shining armor.

In an almost unrecognizable transformation, "Jersey Shore" star Jenni "JWoww" Farley traded in her club gear for a pair of suspenders this Halloween. JWoww and fiancé Roger Mathews got nerdy in Las Vegas as they made themselves into geeks with bowties, plaid pants and taped-up glasses.

Diddy seems to have made a full recovery from his recent car accident, partying at the playboy mansion dressed as Prince. Cassie, who dressed up as a sexy Cleopatra, tweeted a photo of herself and Diddy, with the caption "Cleopatra & Prince! Happy Halloween!!!! #turnup."

Emma Roberts didn't have to look too far for inspiration for her Halloween costume, turning heads in Beverly Hills as she dressed up as Aunt Julia Roberts's infamous prostitute outfit from the classic flick, "Pretty Woman."

Yet, the partying didn't just happen here in the States, before they dropped their new single, "Little Things," One Direction's Liam Payne got heroic dressing up as the caped crusader Batman, parting the night away with Olympic diver Tom Daley, who went as the Penguin.
