Robin Roberts to guest judge 'Dancing With the Stars'

Good Morning America host Robin Roberts announced she'll be the first-ever celebrity guest judge on ABC reality show Dancing With the Stars.

Roberts made the announcement Tuesday on the morning talk show.

"I am nervous ... but you got to step outside of your comfort zone," said said. "I think I am going to take the perspective of those who normally watch at home."

And on Twitter...
