The fact that Halloween fell on a Monday didn't stop stars from celebrating last night in New York City—or Los Angeles, either.
In addition to Heidi Klum and Miranda Kerr's costume parties in the Big Apple, Kanye West and model Anja Rubik threw their own spooky soiree last night at The Darby.
So whose shindig was the best?
Kanye's fete had quite the impressive guest list. Bumblebee Beyoncé, Ryan Phillippe and Naomi Campbell were just a few of the bold-faced names who turned out for his party, where DJ Mick Boogie spun tunes.
Kanye himself was spotted holding hangs with a lovely lady dressed as a devil.
Some revelers, such as Michelle Trachtenberg and Jersey Shore's Vinny Guadagnino, opted to hit both Kanye's and Heidi Klum's bash at PH-D inside the Dream Downtown (her second costumed get-together of the spooky holiday season), while Fergie, dressed as a toddler pageant queen, made Heidi's party her only stop of the night.
The hostess and her hubby Seal were tardy for their own party and didn't arrive until nearly 1 a.m., as they were working on their intricate matching gorilla get-ups. The couple said their primate outfits took nearly 6 hours to complete!
Fortunately, they made it work.
Meanwhile, Miranda Kerr held her own fete at on the rooftop of Catch. Hubby Orlando Bloom was MIA as the Victoria's Secret supermodel wore a sexy ringmaster costume. Partygoers such as Mike "The Situation" Sorrentino, dressed as a policeman, sipped Voli cocktails.
Back in L.A., Adam Levine's annual graveyard bash with his own supermodel girlfriend was the place to be.
Guests such as Christina Aguilera, Lindsay Lohan, Paris Hilton, Lauren Conrad and Leona Lewis all danced with the dead inside the Hollywood Forever Cemetery at the carnival-themed soiree.
Christina, a fellow judge with Adam on The Voice, made a beeline to offer her host a toast after she entered.
Sounds like a great Halloween!
