Celebrities may get to dress up all the time, but that won’t stop them from going all-out with their costumes this Halloween. Although Monday’s the actual day, stars have been celebrating – and showing off their costumes – all weekend.

Halloween queen Heidi Klum turned heads at her Las Vegas party when she arrived on a gurney dressed as the “Visible Woman” in a bodysuit lifted straight from an anatomy book.

Both Kim Kardashian and Julianne Hough were dressed as comic-book villain Poison Ivy this weekend. Kim wore a red wig, ivy-covered minidress, and glittery pumps at a New York party, while Julianne tweeted a picture of herself wearing a green corset top and skintight pants topped with a brown wig.

Jessica Alba attended Kate Hudson’s Halloween party in Los Angeles dressed as a witch, while Gwen Stefani came as a jewelry-covered Cinderella. Zooey Deschanel channeled soul diva Adele with teased hair and winged eyeliner, while Nicole Richie dressed as Jennifer Lopez with a pink tracksuit and heels.

“Glee” star Amber Riley donned a rainbow wig for her costume as Nicki Minaj, while her costar Lea Michele tweeted that “I do think me and @NayaRivera would make a great @Sn00ki and Jwoww.”
