Demi Lovato's life has been action packed this past year -- she released her second album Here We Go Again, headlined a solo tour, dated (and broke up) with Joe Jonas, and filmed Camp Rock 2: The Final Jam. She's currently rocking out every night with the Jonas Brothers on the Camp Rock 2 tour, and turns the big 1-8 today. Happy birthday, Demi!
