She did it again! Last weekend, Kristen Wiig crashed Amy Adams’ opening monologue on Saturday Night Live for the second time! This time she was carried on stage, sang in Mariah Carey’s glitter microphone, and danced in her Christmas-hat with her shakers; all before finally singing the Christmas song with Amy. Kristen and Fred Armisen also reprised their roles as singers Garth & Kat in a surprise appearance on Weekend Update. Screen captures and a video clip have been added to the site.
