Ann Romney to guest host "Good Morning, America" next week

The booking comes on the heels of Mitt Romney’s dominant performance in the first presidential debate on Wednesday. Romney will co-host the morning program alongside Robert’s co-anchor George Stephanopoulos and correspondents Lara Spencer, Josh Elliott and Sam Champion.

She joins previously announced pinch-hitters Stephen Colbert, Oprah Winfrey, the cast of Modern Family and Roberts’ ABC News colleagues Diane Sawyer, Katie Couric and Barbara Walters. Jessica Simpson co-hosted GMA on Sept. 11.
