Today was Robin Roberts last day on Good Morning America before she embarked on a treatment journey to combat her Myelodysplastic Syndrome diagnosis, and it was just revealed that some A-list stars will be keeping Robin's seat warm over the coming weeks.
Oprah Winfrey, Chris Rock, Rob Lowe and the cast of Modern Family will join Diane Sawyer, Katie Couric, Barbara Walters and Kelly Ripa in co-hosting the 8 a.m. hour throughout Roberts' treatment.
"This means so much [that] these friends are stepping up like this," Roberts said. "I love them for that!"
