A Twitter feud has broken out between Kathy Griffin and Demi Lovato's fans.

A Twitter war broke out between two unlikely celebrities: comedian Kathy Griffin and pop star Demi Lovato.

The conversation got heated quickly when Griffin criticized Lovato during a Twitter chat earlier this week when she was asked to call out the "biggest d**che celebrity." The 53-year-old comedian responded: "Probably [Demi] Lovato (she accidentally called her Debbie) ...Plus she should calm the f down bout Lady Gaga gettin' barfed on." The tweet has since been deleted.

During a show at SXSW earlier this month, Lady Gaga had performance artist Millie Brown throw up on her. Lovato criticized this performance, claiming that it glamorized eating disorders.

Griffin's comments inevitably led to the Lovatics lashing out at her, along with Lovato herself.

In response, the 21-year-old Skyscraper singer posted a selfie on Twitter which showed her sticking her tongue out while Griffin stood in the background at an unnamed event. She captioned the pic: "Only a 'd**che' to people I can't stand." Lovato later deleted the pic.

However, Lovato's fans have been tweeting threats and hate-filled wishes to Griffin ever since, and the comedian has since retweeted many of them. Here are a few:

Also, according to Griffin, the tweet that started the whole feud was not actually deleted by her, but the deluge of death threats violated Twitter's terms of conduct, and the social media site itself removed the post.

Lovato, who has stayed out of the conversation since deleting her first response, broke her silence and apologized to Griffin on behalf of her fans, telling them to stop their hateful attacks. The singer wrote: "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 [peace] not hate...."
