Put Nick Jonas in a room with his girlfriend, the former Miss Universe, Olivia Culpo, and your brain cells might explode from overload of hotness. The gorgeous couple walked the red carpet together at 1 Oak's Halloween party in Las Vegas, where they were hosting a costume contest. Nick and his lady friend nailed the couples costume thing, going as a flapper and a guy from the 1920's. We would've preferred if Nick went as a caveman or a swimmer or something that didn't require him to wear a shirt, but we'll put that on our wishlist for Halloween 2015.
