Dayum Demi, back at it again with the Twitter feuds!
Hollywood's sassiest Twitter warrior, Demi Lovato has revisited her feud with comedian, Kathy Griffin, who you'll know as the red-headed funny gal who has sparked outrage for taking a pic with a fake Donald Trump head.
Now, Demz has put her 2 cents in.
Demi's mother also took to Twitter to blast Griffin, writing: "So @kathygriffin states she will continue making fun of people, kinda like she made fun of my daughter @ddlovato for going into treatment."
Wondering what all dis is bout?
Way back when in March 2014, Griffin was asked who the least fave celeb she'd ever met was.
"Probably Debbie Lovato Plus she should calm the f down bout Lady Gaga gettin barfed on."
And now we wait for the clap back...
