Demi Lovato has clearly had it with all the relentless cyberbullying out there.
The "Skyscraper" singer, who is no stranger to venting her thoughts and feelings via Twitter, lashed out last night against those who are sometimes just downright mean.
"It really surprises me the hateful things people say on the Internet," Lovato tweeted. "After all the awareness of cyber-bullying... I mean wow. So sad."
The 19-year-old starlet goes on to add that she's "praying for all the people in the world who feel it's okay to bully people over the internet because if you are one of those people, then.. You must have had something really terrible happen to your childhood or you're really sick in the head. Must suck to be born without a heart."
