Demi Lovato has been an influential force in the entertainment industry for over a decade now. Her characters on Disney Channel's As the Bell Rings and Sonny With a Chance, as well as her roles in Camp Rock and Princess Protection Program will forever be iconic. Her 2008 album Don't Forget and 2009 LP Here We Go Again have also stood the test of time (at least when it comes to my Spotify playlist). We've loved seeing the 28-year-old star grow and evolve into the strong woman she is today. Demi has certainly had her ups and downs, but she continues to come out on top while inspiring others along the way. In honor of the "I Love Me" singer, let's take a look at her amazing evolution.
