What a difference a year makes! Disney starlet Demi Lovato turns 19 today, August 20th, and in celebration we’ve got a gallery of all her looks over the years!

The last year has been an emotional roller coaster for Demi. Her best friend-turned boyfriend Joe Jonas dumped her in May 2010 – well, technically Joe’s father dumped her. Then in this past November, she checked herself into rehab to deal with “emotional and physical issues.” But that was only the beginning for Demi!

Since she left her Los Angeles rehab facility in January, the entertainer has been slowly but surely making her way back into the spotlight. She hopes that fans will find inspiration from her very public struggles, and understand that issues like eating disorders and depression can go away.

“My fans are dealing with some of the same issues. And if I am a role model, then I need to speak up and be there for them,” Demi told Access Hollywood.

Demi definitely deserves something special to celebrate her nineteen birthday for overcoming so much in the last year, but the actress/musician is opting to spend this Saturday celebrating something extremely different – Kim Kardashian’s wedding! “I’m so excited, Kim’s wedding falls on my birthday. So, it’s going to be my birthday and I get to spend it at Kim’s wedding,” Demi revealed.
