Demot O'Leary: Louis Walsh is the 'dirtiest' X Factor judge
Dermot O'Leary thinks Louis Walsh is the dirtiest judge on this year's 'X Factor' panel - also featuring former Spice Girl Mel B, Cheryl Fernandez-Versini and show boss Simon Cowell
Dermot O'Leary claims Louis Walsh is the dirtiest 'X Factor' judge.
The 41-year-old presenter - who has hosted the ITV singing competition since 2007- has revealed that Louis, 62, is the most ruthless member of the judging panel ahead of his co-stars former Spice Girl Mel B, Cheryl Fernandez-Versini and even the show's boss Simon Cowell.
According to Dermot, the entertainment manager often resorts to unsavoury tactics in a bid to win the show.
He told The Sun newspaper: "I love it when the panel is fun and when they are a bit spikey with each other, so long as they don't resort to the proper dirty stuff like Louis does.
"If I was a contestant, Louis would be the judge I'd want because when we go to the studios he is the dirtiest judge we have."
However, Dermot insists Louis' "unorthodox" antics make him the most "valuable" judge as his "unconventional" mentoring methods keep the show interesting.
He explained: "He's unorthodox and unconventional but I couldn't make the show without Louis.
"I adore him."In many ways he's the most valuable person on the panel. I can always rely on him to give me a tiny bit of insanity.
"He laughs when everyone else cries and cries when they laugh. He walks to the beat of his own drum. He's an extraordinary man."
