Top Videos: Mariah Carey Butchers Her Own Christmas Song, Pug Gets a Bath

This week, Mariah Carey performed "All I Want for Christmas Is You" live at the Rockefeller Center Christmas tree lighting, making a strong case that the producers should probably just hire the girl from Love Actually for next year's ceremony.
