'Good Morning America' Maps Strategy to Get Along While Robin Roberts Is Out -- Including Deployment of a Fleet of Celebrity Guest Hosts; Some Impressive Names Are on the List (Including at Least One Former Queen of Daytime Talk) AP

"Good Morning America" is working on filling the void left by longtime host Robin Roberts’ medical leave from the morning show, and ABC appears to be lining up a roster of celebrities to fill in as guest hosts.

Comedy Central host Stephen Colbert will be among the first up, the Associated Press reports. Other substitutes will include the cast of ABC's "Modern Family," along with Oprah Winfrey and newswomen Barbara Walters, Katie Couric and Diane Sawyer, according to the piece.

The program will feature a different "Modern Family" cast member each day for a week, while actor Rob Lowe is also slated to appear as a guest host, according to Tom Cibrowski, the show's senior executive producer.

ABC is also putting the finishing touches on arrangements for first lady Michelle Obama and her political counterpart Ann Romney to fill in, as we reported earlier.

Roberts, who has the blood and bone marrow disease MDS, left “GMA” Aug. 30 and is out indefinitely. She is scheduled for a bone marrow transplant this week.
