Feud alert! Demi Lovato had a bit of a Twitter tiff with comedienne Kathy Griffin, who started it, actually.

Griffin called Lovato an unsavory term, Lovato replied (and swiftly deleted it) and then Lovatics took over, defending their heroine with vicious comments about Griffin until Lovato herself called off the dogs.

Griffin was engaging in a Twitter chat with fans when she issued this offending tweet. She jokingly referred to the singer as "Debbie."

Lovato replied, sharing what appeared to be an older photo of herself sticking her tongue out, with Griffin on a TV in the background, writing "Only a 'douche' to people I can't stand." Since Lovato has pink hair now and she boasts blonde bangs in the photo, it may have been old, although she does change her hair with alarming frequency, so you never know!

However, the reply has since been deleted, but nothing ever dies online and it was captured here.

Lovatics went to work, wishing all sorts of deadly diseases on Griffin and making death threats. Griffin seemed to be enjoying the tweet heat, and RT'ed many of the mean transmissions, making a point that Lovatics were out of control and musing that those who were brutal to her could not be representative of the entire fanbase.

Eventually, Demi herself stepped in and asked the Lovatics to stop with the hate, which was a classy move. Since she is the poster girl for addressing one's issues and anti-bullying, this was the proper response.

Below is Demi's request for a ceasefire on the hate tweets.

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 somethings 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 ✌️not hate....

We're not sure why Griffin feels the way she does about Demi. Maybe it was a joke on her part. Maybe it wasn't. Hopefully they can call a truce after the ensuing drama.
