Oprah to Guest Host GMA for Robin Roberts

This will be Oprah's first return to daytime TV since leaving her show last year

Oprah is coming back to daytime - temporarily.

While "Good Morning America" anchor Robin Roberts is recuperating from her bone marrow transplant, the show's viewers will be treated to perhaps the world's most famous guest host. ABC announced that its lineup of substitute hosts includes the queen of daytime television, Oprah Winfrey.

The temporary role will be Winfrey's first return to daytime network TV since the ending of her talk show in 2011.

In addition to Winfrey, Barbara Walters, Diane Sawyer, Katie Couric and others will also be brought onboard to host the show. Interestingly, Winfrey will be going toe-to-toe with best friend Gayle King, who hosts "This Morning" on rival network CBS in the same time slot.
