    The latest occasion was an interview with TV show Access Hollywood, where the conversation soon moved to her nudity in the upcoming film, due to open in the USA on June 2 reports China Daily.

    "You have a very nice tush," the show's Nancy O'Dell said of the nude scene she shares with Vaughn.
