This has to be one of our favorite Demi performances!
Demi was lowered to the stage in a bubble of sorts, all dressed in black (and a little gold) and an a-mahzing studded leather jacket and sky high heels.
She literally got the crowd jumping for the high energy performance.
After her Divas performance, Demi tweeted: "How great was @MileyCyrus's performance tonight? Beautiful, stunning and bad ass. All in one #rockstar"
Miley repaid the compliment, tweeting: "@ddlovato well you know the feelings mutual boooo.... Beautiful, stunning and don't get me started on THAT ass. Haha ❤good seeing u 2day :)"
