Good Morning America viewers have noticed Robin Roberts' recent absence from the show - but how long will she be gone? Roberts, 64, became a staple on ABC after joining as a coanchor in 2005. While wrapping up the July 24 episode of the morning show, Roberts announced she was taking time off with wife Amber Laign. In addition to Roberts' break, George Stephanopoulos was on vacation - with ESPN's Joe Buck filling in. Roberts' role, meanwhile, was temporarily taken over by Rebecca Jarvis.
