Jennifer Lopez and Casper Smart Are Scary Sexy on Halloween

Jennifer Lopez and Casper Smart don't even know how to just be frightening for Halloween: they have to be terrifying and hot at the same time. To celebrate Oct. 31 at Heidi Klum's party, the couple wore creepy (and yet gorgeous) skeleton makeup with their all-black outfits for what Jennifer called "haute couture skeleton" costumes. Of course, J Lo opted for a low-cut Michael Costello lace dress with floral details, pairing the piece with long leather gloves for an extra sensual touch. Keep scrolling to see more photos of the look, then check out what other celebrities wore to celebrate Halloween.
