From star-studded costume parties to proud parents taking out their tiny trick-or-treaters, Hollywood's hottest celebs love to show off their spooky sides!
Since the Halloween season is upon us, we're taking a look at some of the best celebrity costumes of ALL time ... or at least the past couple years.
And no one does Halloween quite like Heidi Klum!
Back in 2013, the supermodel showed up at her annual Halloween party completely transformed into an old woman. The "America's Got Talent" host was unrecognizable, sporting a collection of realistic wrinkles, age spots and varicose veins.
The biggest costume showdown each year is between the hosts of daytime TV.
Kelly Ripa and Micheal Strahan made us do a double take when they made their Halloween debut as Kim Kardashian and Kanye West.
With the reality star's big booty in tow and the rapper's signature frown, the talk show team completely embodied the power couple. (Matt Lauer in a red "Baywatch" one-piece also earned top marks!)
And, Miley Cyrus nabbed a spot on our best costumes list for channeling another skin-baring star: Lil Kim!
Donning a purple wig and that infamous purple shell pasty, the "Wrecking Ball" singer totally nailed her impersonation of the colorful rapper.
