In addition, Joe Jonas -- who previously served as a guest judge during last summer's ninth-season audition in Dallas -- will perform a duet of "Make a Wave" with fellow Disney Channel star and girlfriend Demi Lovato on the results show.
Following last week's results show, Fox had announced that "Teen Idols" would be the theme for this week's performances.
The live results show will air the following night at 9PM ET/PT.
