Moon then chimed in by comparing Irvine to Psycho character Norman Bates.
Talent shows such as X Factor are supposed to celebrate talent but ritualistic humiliation of contestants is also part of the formula.
English reality TV celebrity Simon Cowell is proof of this.
He built a career on his acidic assessments of contestants on shows such as Pop Idol, The X Factor, and American Idol.
However, while Cowell's criticism always has a hard edge, there is a degree of calling "a spade a spade" to his delivery. You might not agree with his tone but often as not you might agree with the sentiment.
It's difficult to say that about Kills and Moon's performance.
In a strange reflection of modern life, the couple now find themselves at the centre of an online tirade.
Many of the comments are similar in tone to the bullying they are being criticised for.
I could comment that people need to take the higher ground on this issue if they really want to stamp out bullying but that would be pointless.
For Kills and Moon, it's a case of live by the sword, die by the sword.
