GMA in Search of Robin Roberts Celebrity Subs

*Even though “Good Morning America” won’t be the same without Robin Roberts, she’s making sure viewers will have a good time in her absence with a list of fan favorite celebrities.

Roberts goes on medical leave in a few months for myelodysplastic syndrome – a serous blood and bone marrow disease. She’s already begun chemotherapy treatment and will endure a bone marrow transplant soon.

Among the celebrity co-hosts hopefuls are Diane Sawyer, Charlie Gibson, Barbara Walters, Chris Cuomo, Connie Chung, Joan Lunden and several others.

According to reports, each candidate will be Roberts for a week, who may be out for up to four months.
