On 'Good Morning America' (weekdays, 7AM ET on ABC), Robin Roberts and her fellow anchors preview her appearance on 'Hannah Montana.' In the clip, Roberts does little to reassure a nervous Miley Cyrus.

Roberts' appearance takes the form of a mock interview on the set of 'GMA.' Cyrus admits to being nervous and asks whether Roberts would give an honest opinion if the interview didn't go well. "Probably not," replied the anchor. So, Cyrus makes a subtle dig at Roberts' appearance in retaliation.
