Former X Factor New Zealand judge Natalia Kills faced online backlash after bullying a contestant live on air.

The 28-year-old British singer, whose real name is Natalia Noemi Cappuccini-Sinclair, along with her husband Willy Moon, accused Joe Irvine of copying her spouse.

"As an artist who respects creative integrity and intellectual property, I am disgusted with how much you have copied my husband. From the hair, to the suit, do you not have any value or respect for originality? You're a laughing stock, it's cheesy, it's disgusting, I personally found it absolutely artistically atrocious," Kills said.

"I am embarrassed to be sitting here in your presence, having to even dignify you with an answer of my opinion."

"To me it just seems a little bit cheap and absurd. It's like Norman Bates dressing up in his mother's clothing. It's just a little bit creepy," added Moon. "I feel like you're going to stitch someone's skin to your face and then kill everybody in the audience."

The blood bath continued when Natalia chimed in once again. "I'm going to say it. It's disgusting. You make me sick. It's absolutely disgusting. You have no identity. I can't stand it. I'm ashamed to be here."

The couple were instantly fired for their insensitive comments.

Meanwhile, Twitter exploded with funny memes of Kills and Moon.
