The "Stone Cold" singer courted controversy online when she criticised Carey for "dissing people", and fans of the pop diva immediately took aim at Lovato's Twitter and Instagram accounts.
Lovato responded to her haters, by tweeting, "Damn I gotta quit sayin." And added she might have to take a hiatus from social media for a while.
"Bye Twitter And insta," she wrote.
"I like snapchat cause I don't have to see what some of y'all say... But why do people actually care about what I say? That one time I started my own charity providing mental health care for people who can't afford it and this is what y'all talk about. And people wonder what's wrong with the world. Pay more attention to good than bad."
