Oscars 2013: The best and worst moments

After finally returning to "Good Morning America," Robin Roberts showed off how hale and healthy she is during ABC's Oscars pre-show. She looked gorgeous in a sleeveless blue velvet Marc Bouwer gown as she interviewed celebrities and Academy Award nominees as they walked the red carpet. It's good to have you back, Robin!
