Don't Miss:

After days of pre-Halloween parties, October 31 finally arrived, and stars pulled out all the spooky stops. For Kim Kardashian‘s LIV party in Miami, the Kardashian clan, including  Kim, Kanye West, Kourtney (as Batgirl), and Scott Disick (as Robin) joined forces to pay homage to the Caped Crusader himself, Batman (played by Kanye, of course). And it wasn’t just their collective costumes that tied them together: Kim tweeted that there were also “cars to go with our theme!” That’s one very Kardashian-style Halloween outing! (Batmobile included.) Click through the gallery below to see more stars in costume!
