The heiress and the boyfriend, Paris Hilton and River Viiperi, decided to become superheroes for one night to attend Rihannaâ€™s Halloween bash held at the Greystones Manor in West Hollywood, California on Wednesday (October 31).
There is no doubt Batman was Robinâ€™s sidekick for the night. Paris looked incredibly sexy as a skanktastic Robin, while River (as Bat. Man) was simply an accessory to the socialiteâ€™sÂ insatiableÂ need for attention.
