Katie Couric's triumphant return to daytime television just got a little more interesting.
Couric, who is filling in this week for Robin Roberts as a co-host on "Good Morning America," will have an unlikely competitor in her old "Today" show chair: Sarah Palin.
NBC announced on Saturday that Palin--whose infamous 2008 interview with Couric on CBS was one of her vice presidential campaign's lowest moments--would be the co-host of the show on Tuesday, promising the former Alaskan governor would "reveal a different side of her."
"Today" is also cranking up the Peacock promotional machine for the surprise appearance of a yet-to-be-revealed "legend" on Monday--both moves aimed at blunting ABC's Couric coup.
But Couric and Palin won't be the only women vying for morning viewers this week. On Monday, Oprah Winfrey is scheduled to be a guest on "CBS This Morning"--the first time the former Queen of Daytime has appeared on the show since her best friend, Gayle King, signed on as co-host.
