Miley Cyrus, Joe Jonas & Demi Lovato Perform on American Idol Results Show

American Idol viewers received a double live treat last night.

The results show, which saw voters send Paige Miles home, also saw a triple teen threat of Miley Cyrus, Joe Jonas and Demi Lovato bringing the house down.

For all our criticisms of Miley, you have to give her credit, the girl is a good live vocalist, a true stage presence with a husky, powerful voice beyond her years.

Although the writhing and spontaneous convulsions during the chorus of "When I Look at You," her track from The Last Song? No idea what's going on there.

Perhaps Liam Hemsworth knows a little something about it:

Miley Cyrus - When I Look at You (Live on American Idol)

What did you think of Miley Cyrus on Idol? Did she bring her A-game? Are you psyched for her first huge non-Hannah Montana role, as she focuses on acting?

In addition to Miley, new couple and dueling music stars Joe Jonas and Demi Lovato performed "Make a Wave." They certainly did in real life by coupling up.

Follow the jump to see the lovebirds in action ...
