Olivia Munn was scorching hot on the Tonight Show wearing a short red dress and the ever present Christian Louboutin platform high heels. She was certainly self conscious about the length, or lack thereof, of the that dress as she kept pulling it down her thigh while she was sitting. The dress was cut in an asymmetrical cutout shape that kept riding up exposing more of her left thigh than she liked. Gerard Butler sure enjoyed the view as he even commented on how lovely her legs were. She was an animated guest and quite entertaining as she showed her modelling technique.
