Dannii got into trouble judging the X Factor back in 2009, when she appeared to judge a contestant on his sexuality rather than his singing voice.

Danyl Johnson sang And IÂ’m Telling You (IÂ’m Not GoinÂ’) from the musical Dream Girls, changing the lyrics to reflect that he was singing a traditionally female part.

Dannii said after the performance: “Turning a girls' song into a guy's song, but if we're to believe everything we read in the paper, maybe you didn't need to change the gender references?”, prompting gasps from the audience.
