Demi Lovato has had to step in to warn her fans to stop cyber-bullying comedienne Kathy Griffin.

The two women started a Twitter feud after Griffin reportedly called Lovato a “douche” and the singer’s fans quickly stepped in to defend their idol.

The messages started becoming so violent and hateful that Lovato was forced to step in, telling fans: “I love you guys so much but y'all gotta chill with sending hate towards other people. Regardless of what they say or do.. The cruel things some of you are saying can really, REALLY hurt people. It's called cyber-bullying and some things should NEVER be wished upon EVER. No matter WHAT. It makes me so sad to see how mean people can really be after all I've spoken out about anti-bullying.

"Be an example for other haters. I know my #Lovatics are better than that. I really appreciate you guys always having my back but this is going way too far. Please spread [peace] not hate...."

She later tweeted directly to Griffin saying: “@kathygriffin no one should ever wish those things upon ANYONE. I apologize on others behalf. I do NOT approve of that at all. Sorry 4 that.”
