And yes, the song has been sung on the show before, by X Factor favourite Diana. The news has caused outrage among the other acts, who think Diana has had an unfair advantage, and probably made Dannii Minogue cry again (although we're still surprised that she was able to produce real, hot, human tears).

A source has said:

"Tempers are running high. They feel it is the latest in a series of stunts that have left them wondering if the competition has already been won."

Meanwhile, Diana has caused more controversy by reportedly doing the dirty with little Eoghan Quigg, who looks five years younger than Diana despite being just the one.

Another convenient source said:

"Everybody knows they're a couple now."

We don't know what disturbs us more now...
