“‘I GET KNOCKED DOWN BUT I GET UP AGAIN AND YOU’RE NEVER GONNA GET ME DOWN!!!!’ #storyofmyLIFE,” Demi tweeted. “There’s nothing more upsetting and hurtful than people having no regards to someone’s private life and using the web to bring people down.”

She continued, “The things people do can affect/hurt others. Even if you don’t think I see things.. I’m not a celebrity, I’m an artist & most importantly human.”

Earlier in the month, Demi posed with Lucy Hale backstage at her SAP Center show in San Jose, Calif.

@J: Speak about knowledge you actually have before posting lies on the internet. There’s no proof of leaked nude selfies of Demi, so shut up. Demi posted that tweet because she’s tired of people ridiculing her weight on Twitter.

@heather: Haha, we share the same name. Isn’t that ironic? :)
