Katy Perry as Daria's Jane Lane. Jessica Simpson in pigtails and a leather corset. Rihanna toting a tiara and scepter. It's November 1, y'all. The Catholic Church and other Christian denominations observe this as All Saints' Day, but perhaps a bit more widely spread, this is also the day you thumb through everyone's Halloween Facebook/Twitter/Instagram photos regardless of whether you and your friends spent the day in costume or in your PJs by candlelight, crossing your fingers for your power to come back #Sandy. To make it easier for you, we rounded up some favorite (and flagrant) celebrity costumes from All Hallows' Eve.
KP steals our hearts, repping our favorite '90s MTV animated series Daria — a show she's already professed her love for via nail art — with her real life BFF Shannon Woodward as Miss Morgendorffer herself. J. Simp celebrates Halloween dressed as a milk maid or an Oktoberfest girl or... Okay, honestly, we have no idea, but we DO know she looks amazeballs 5000, and that's good enough for us. Robyn Fenty accepts her crown as the "Queen of the 2012 West Hollywood Halloween Carnaval" in a simple black dress, saving her real Bad Gal RiRi costume for the party itself.
Apparently, Three 6 Mafia's Juicy J is not the only one drawn to weed-themed Halloween costumes. Both Ri and Lady Gaga (seen pictured here with her makeup artist Tara Sarvelo dressed as, well... Lady Gaga) masqueraded as different lady forms of green for the holiday. Uproarious? Potentially offensive? Sure. But umm, this also happened.
Adam Lambert reprised his white-haired, top hat-clad "Glampire," while Selena Gomez slicked on some eyeliner whiskers and a black nose for a quick, easy cat costume. Chloe Grace Moretz proves her horror chops, decked out in Tim Burton-ready, ghoulish goth togs for Jonathan Ross's Halloween party. Which celeb Halloween costume was your favorite?
