Judges L.A. Reid, Simon Cowell, Paula Abdul and Nicole Scherzinger traded blows during the first live X Factor final show.
Nicole and Simon in particular seemed to be butting heads, with the Pussycat Doll singer trying in vain to outwit him.
However, most of the criticism has been directed at Nicole's shallow comments - there's a growing consensus that she fails to add anything insightful or meaningful to the panel.
At one point, Simon seemed to be frustrated at her vapid comments to the hopefuls, snapping "What do you mean it gave her wings, Nicole?" Nicole floundered before responding "She just soared."
The singer, who controversially replaced Cheryl Cole in the judging line up, was booed by the audience for criticising L.A. Reid just half an hour into the show.
Speaking to E!, Nicole tried to laugh off the bad blood with Simon; "I am pretty tough. I know how to handle [Simon] but sometimes I've just got to bite back," she said. "I can't help it, especially when he talks about me not connecting with my contestant when I know how hard I've worked with them and the time I've spent."
Perhaps Cheryl should count herself lucky...
