Kelly Ripa, Chris Rock, Oprah Winfrey, and cast members of Modern Family will be among the guest hosts of ABC's Good Morning America, during the absence of Robin Roberts, who has left the show for an undetermined leave, according to The Hollywood Reporter.

Roberts is set to undergo a bone marrow transplant to treat her recently diagnosed myelodisplastic syndrome (a rare form of leukemia).

In addition, ABC news personalities Diane Sawyer, Katie Couric, Barbara Walters and Elizabeth Vargas will act as guest hosts alongside current anchors Josh Elliott, Sam Champion, George Stephanopoulos, and Lara Spencer.
