Robin Roberts to Guest Judge on 'Dancing with the Stars'

Guess who's heading to the "Dancing With The Stars" ballroom? Robin Roberts!

The "Good Morning America" anchor will be a guest judge on the hit ABC show, joining Len Goodman, Bruno Tonioli and Carrie Ann Inaba at the judges table on March 31.

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

Roberts also asked viewers for their judging advice on Twitter:

The celebrities will each be asked to dance a routine that encompasses the "most memorable year of their lives," promising for a night of emotional backstories and performances.

While she's not putting on her dancing shoes this time around, Roberts marked her 50th birthday on "GMA" in 2010 by dancing the cha-cha with pro Maksim Chmerkovskiy.

Roberts will be one of many guest judges on "Dancing" this season, including former pro Julianne Hough and singer Ricky Martin.
