One would argue that this was downright criminal.
Fiona Apple was performing in Portland, Ore., with Blake Mills on Thursday night when a so-called fan began heckling the 36-year-old songstress.
"Fiona! Get healthy! We want to see you in 10 years!" the female heckler yelled out, according to Stereogum.
Apple was said to be visibly distraught and proceeded to yell back, "I am healthy! Who the f--k do you think you are? I want to get the f--k out of here. I want the house lights on so I watch you leave!"
The lights reportedly did come on and the very vocal audience member threw out one more remark while exiting, saying, "I saw you 20 years ago and you were beautiful!"
Apple subsequently began to cry and expressed her frustration to the crowd. She managed to collect herself enough to perform "Waltz (Better Than Fine)," but she sang it while slightly sobbing.
She soon became very emotional again and, apologizing to the audience, walked off the stage, thereby bringing the show to an end.
