A few weeks ago Robin Roberts began a leave of absence from Good Morning America in order to focus on her treatment for MDS, a blood and bone marrow disease. Besides the more serious-minded guest hosts – like Barbara Walters and Oprah – ABC will also try to have some funny folks in. Coming up soon are Stephen Colbert and Rob Lowe. Also, they’re planning on having a week in which a different member of the Modern Family cast will host each episode. (My DVR is already set for when the French Bulldog hosts.) The comedian (or dog) guests won’t have to concern themselves with much news, instead they’ll be appearing in the show’s more pop culture focused second hour. Either way, the earlier in the day you get to see Colbert, the better.
