Jennifer Hudson performs on 'GMA'

Jennifer Hudson took part in ABC News' "50 States in 50 Days" event this morning as she performed a set at the Newseum in Washington, D.C. on Good Morning America. One fan even camped out overnight to wait for the doors to open at 6:30 a.m. this morning. But it was not just Jennifer's singing that got people talking. Take this story, for instance, from CelebTV.com about how Diane Sawyer & crew admired Jennifer's $5,000 engagement ring.
