It's Halloween! On a Monday!!! What's so awesome about this and triple exclamation-worthy is that all of the CELEBratory parties happened this weekend (to allow for sleeping-in while still in your superhero makeup or sexy leopard Snuggie, a'la Snooki in Vegas), and now our toiling, tricked-out fingers can TREAT you with the finest of Halloween costume roundups. From the Mexican food-catered environs of Kate Hudson's Palisades party attended by everyone from Leslie Mann dressed as Kreayshawn (SHE AIN'T BASIC) and Nicole Richie as JLO to Glee parties featuring Lea Michele as a white swan and Amber Riley as Nicki Minaj. Among the more colorful costumes, Kim Kardashian was a flame-haired Poison Ivy and Mandy Moore was utterly unrecognizable as a hair metal rocker. But what about Justin Bieber, Selena Gomez, and all the rest of the celebrity gang? Right this way my pretties, MWAAAA HAAAA HAAAAA!
