Critics of reality television probably think this sort of thing is par for the course, but it's not. Viewers were horrified - and so, eventually, were TV3 bosses who reacted yesterday afternoon by sacking Kills and Moon from the show.
Maybe there's no such thing as bad publicity, but after a string of TV3 apologies after a string of issues with the judges, this must have been the last straw.
With Paul Henry set to launch his new show, TV3's complaints department, and maybe the odd lawyer, will soon be far too busy to deal with ongoing X Factor problems.
But seriously, The X Factor is a show watched and loved by kids as well as adults. Its stars are role models to both the contestants and the viewers.
We can expect a bit of banter, and even a spot of what might look like manufactured drama, but the nation's tolerance - as well as that of sponsors like McDonald's - would seem to only extend so far.
