Before joining the all-star cast of Friday night's Hurricane Sandy: Coming Together telethon, Christina Aguilera stopped by Late Night With Jimmy Fallon to chat. Following in the unusual-instrumentation footsteps of Carly Rae Jepsen, Aguilera got together in Fallon's office with the host, the Roots and a bunch of office supplies for a special rendition of  "Your Body," the lastest single from her forthcoming new album, Lotus. Fallon sets the beat with a few notes on his iPhone keypad and Aguilera plays the stapler.
