Jon Hamm
Jon Hamm has never publicly declared a no-nudity clause, but the actor has never actually been seen in the buff for any role. Movie magic managed to uphold his modesty in Bridesmaids, which was the closest Hamm ever came to wearing only a smile on-screen. In real life, unfortunately, a photo of Hamm’s private parts was sold to the tabloids by snooping paparazzi.
