Demi Does "Jimmy Kimmel"

Demi Lovato appeared on "Jimmy Kimmel" to promote a wide range of projects, including her live performance of "Make A Wave" on "American Idol" tomorrow (March 24) and the second season of "Sonny With A Chance". She also chats about her Barney days, her relationship with Joe Jonas, and her music taste. Normally she comes off as entitled and stand-offish in her interviews, but she's actually sweet here.
