Watch Demi on Jimmy Fallon, where she talks about her song Give Your Heart a Break hitting number one and the big honor of being a VMA nominee and performing at the pre-show.
We can't wait to see Demi before the 2012 VMAs!
Demi also dished on X Factor and what it's like to work with Simon Cowell. If the clip is any indication of the teasing they give each other, it's going to be a fun season watching Demi and Simon go head to head.
Watch Demi with a mouthful of mints, spitting them into Simon's hand--so funny!
Demi recently spoke with MTV about preparing for the VMAs, joking that she wants to be "well rested" so she "doesn't look like a hag!"
We can't wait to see what she has up her sleeve because she's being pretty secretive about her performance.
