Demi bids farewell to 'Sonny with a Chance.'
Just months after leaving a treatment facility for an eating disorder, Demi Lovato is proud to be back in good health and tweeting about it!

The former Sonny with a Chance star posted a pic of herself in a white bikini, writing: 

“I’ve been working so hard to get healthy and fit.. I can’t believe I’m about to do this but I’m so excited.. Here’s my bikini time body!”

She later wrote: “It hasn’t been easy, but it starts with a commitment to yourself.. Your mind.. And your soul. And trust me, I’m still working at it!!”

Just last month, the singer/actress went on a mini media tour, talking about her issues in the hopes that it would help other girls out there that may be dealing with the same insecurities. 

Demi chatted with Good Morning America anchor Robin Roberts this past April, and disclosed how getting bullied led to an eating disorder and bouts with cutting when she was younger. “I literally didn’t know why they were being so mean to me. And when I would ask them why, they would just say, ‘Well, you’re fat.”  Demi seemed to be on the road to recovery and was eager to tell her story. She said on GMA, “The real reason why I’m sitting down with you is to open up the eyes of so many young girls, that it doesn’t have to be this way.”

Demi isn’t the only former Disney star to show off her bikini body this week. Miley Cyrus flaunted her two-piece figure wihle she and her family soaked up the sun in Brazil over the weekend.
