'American Idol': Demi Lovato Performs 'Confident' with Top 10, Slays 'Stone Cold' [WATCH]

Idol has mostly moved away from big group performances in recent singles, but the old school tradition was brought back this week as the top 10 contestants joined Lovato for a rousing rendition of "Confident." While the four remaining boys (Dalton Rapattoni, MacKenzie Bourg, Trent Harmon and Lee Young) were relegated to playing backup on guitar, contestants La'Porsha Renae, Avalon Young, Tristan McIntosh, Gianna Isabella, Olivia Rox and Sonika Vaid all got to sing a line or two alongside Lovato, with mixed vocal results.

But, the real stunning moment of Lovato's Idol cameo came when she went solo for "Stone Cold." Calling back slightly to Kelly Clarkson's amazing "Piece by Piece" performance on last week's show, Lovato was accompanied simply by a piano while she sang the heartbreaking ballad. And, in typical Demi Lovato fashion, she totally killed it. There was no taking the big, bold notes down an octave here - Lovato 100 percent went for it.

In addition to the shocking results, in which Olivia Rox and Gianna Isabella were sent home, Idol judge Harry Connick Jr. also performed his new single "I Do (Like We Do)" on the show.
