When it comes to holidays celebrities get into, Halloween comes out near atop the list. That's because, aside from access to makeup departments, celebrities have dressing up in costumes down pat. Just check out some of the impressive costumes on Instagram. There were some amazing and hilarious couples costumes like Fergie and Josh Duhamel's Karl Lagerfeld and Choupette (his beloved cat) getups (above). Or what's cuter than celebrity spawn dressed up as the sweetest ghoul around? See the celebrity costumes below and gather inspiration for next year.
Rande Gerber and George Clooney's Casamigos Tequila Halloween party was simply the hottest ticket in Tinseltown. Turning up the heat? Cindy Crawford and hubby Gerber in this Hell's Angels look.
At the same party, Gwen Stefani was a sexy cowgirl.
While Channing Tatum and Jenna Dewan-Tatum were a pair of Cats-in-the-Hat.
Also at Casamigos, Jessica Alba "invented post-its" with her model pal Kelly Sawyer as Romy and Michele.

Also from the Klum party, Jennifer Lopez is the sultriest "haute couture skeleton" ever.
Leave it to Miley Cyrus to have a sense of humor. The pop star dressed up as a (sweet?) tooth with her friend who was a tooth fairy.
