Claims of dirty tactics and song-stealing are flying round the production offices at the X Factor.

And the allegations were made public when X Factor host Dermot O’Leary was interviewed by Alan Carr on his talk show “Chatty Man.”

Dermot made the revelation that the mentor of the groups category, Louis Walsh is the “dirtiest judge:”

“He’s the judge that nicks songs; before you know it his act will have a song and another judge will be going, ‘Hang on, I picked that for my act’.”

It’s not the only scandal to taint long-standing judge Louis recently.  He caused controversy when he confided to Xtra Factor host Sarah-Jane Crawford that he had never wanted so many members in the boy band Stereo Kicks; the popular boy band was formed from individual auditionees and currently has eight member.

Louis was tackled about his comments on the X Factor and make an apology, but Simon Cowell still said he had acted in a “disgraceful” way and offered to mentor Stereo Kicks himself.

Dermot seems rather fond of Louis, confiding to Alan Carr that he “does say things every now and again and, bless him, he wears his heart on his sleeve.”  Dermot, who has hosted the X Factor for eleven years, went on to say that Louis Walsh is one of the reasons he is still happy to be a part of the popular talent show:

“I honestly couldn’t make the show without Louis… just at the last minute I know Louis’ going to come out with something mental and I’ll just be like ‘thank you!’ and immediately beat up on him. I don’t know where I’d be without him, he’s brilliant.”
