During a Twitter chat earlier this week, the red-haired comedian shared that the "biggest douche celebrity was "Probably [Demi] Lovato. Plus she should calm the f down bout Lady Gaga getting barfed on."
Not finding any humor in the funny lady's remarks, the "Heart Attack" singer took to Twitter, posing a selfie while she's sticking out her tongue with Kathy in the background.
Since deleted, the caption read, "Only a 'douche' to people I can't stand." Of course, the singer's Lovatics came out in full force and Ms. Griffin has been retweeting their threats on her own page.
