The Girls Aloud star and Walsh have been at each others throats since Louis told her 'it's not all about her' on a live show.
And as their fighting continues the 27-year old has hit out at Louis.
The Promise This singer told X Magazine: 'It was really out of context, it was random, I just said to him [Louis] 'If there's a problem, come to my dressing room, and let's have it out.
'Why are you shouting at us? What's that all about?''
She added: 'I hadn't even mentioned myself when he said 'it's not all about you - you're making yourself look stupid!' No, actually, you are Louis.'
Cole also went on to joke that Walsh thinks he is the star of X Factor.
She said: 'Maybe he might think it's all about the judges because he's a judge but for me, it's about my girls and how they perform.
'I really don't care what Louis' opinion of me is.'
