Whether she's fighting with Miley Cyrus or defending Selena Gomez, Demi Lovato hasn't been able to get away from Hollywood drama. Most recently, the pop star got into a heated Twitter argument with 53-year-old comedian Kathy Griffin.
When Kathy was asked who the biggest celebrity jerk she's ever met is, the star immediately wrote (then deleted) Demi's name.
Demi was definitely not too thrilled about Kathy's horrible comment and posted the photo below on Twitter with the caption, "Only a [jerk] to people I can't stand."
Demi deleted the tweet immediately, but not before Kathy saw it!
Do you think haters need to leave Demi alone? Was the photo she tweeted funny or did she go too far? Sound off in the comments below!
