Stars were scattered around New York City and Los Angeles, dressed in terrific and tacky trends. In New York City, Jennifer Connelly stopped by to visit David Letterman, looking like she just stepped off the Balenciaga Spring 2010 runway, completely threaded in the designer's duds. Nearby, Snooki hit MTV Studios, wearing her favorite bedazzled trucker hat, Coach Bag and Bebe belted coat with a leopard dress over sweatpants, adding UGG slippers for a final touch!
