Amy AdamsAndy Samberg says Amy Adams turned down filming a “very dirty” song for a Saturday Night Live skit once — but for the sweetest reason.While appearing on an episode of The Lonely Island and Seth Meyers podcast released last week, Andy — who makes up one third of the Lonely Island comedy trio alongside Akiva Schaffer and Jorma Taccone — revealed why Amy refused to do the NSFW song while hosting SNL in March 2008. The comedian explained that the Oscar nominee decided against it to protect the young fans of her film, Enchanted.At the time, the Disney movie, in which Adams played princess-to-be Giselle, had just been released months before she appeared on the late night sketch show.
