"Judge Me Tender" - Hannah fills in for Kara DioGuardi alongside judges Andy and Byron on reality show "America's Top Talent." Her stint as a guest judge turns complicated when Oliver auditions and delivers a knock-out performance. Oliver turns into a heartthrob overnight and gets so caught up with the attention, he neglects Lilly, so when he is scheduled to perform again, Lilly pressures Miley to give him a bad review so he won't advance to the next round. Much to their dismay, he delivers another great performance and Miley finds herself stuck between being honest or helping Lilly. Meanwhile, as punishment for receiving a traffic ticket, Robby makes Jackson clean the attic. When another ticket arrives, father and son discover a case of mistaken identity, in a new episode of "Hannah Montana," premiering Sunday, October 18 (7:30-8:00 p.m., ET/PT) on Disney Channel.
