Former BFFs Kim Kardashian and Paris Hilton were unwitting costume rivals on Halloween when both arrived at different parties dressed in Batman-themed costumes with their boyfriends.

While Kim was celebrating her birthday with a big bash at LIV Night Club in Miami, Paris hit up Rihanna’s lavish shindig at the Greystone club in Los Angeles.

Kimmy K and boyfriend Kanye West sported some uber-authentic looking Catwoman and Batman costumes, looking serious and chic. Paris and her beau, River Viiperi, went for a comic-book look, with the celebutante dressed as sidekick Robin and River done up as the caped crusader.

But who rocked the Batman look the best?
