X Factor's Louis Walsh has hit back at Gary Barlow for criticising his mentoring of the Overs category in the past series.
Gary, who is in charge of the Over 28s this year, hit out at how the category had become known as a "joke" in past series.
Discussing Gary's comments, Louis hit back: "Gary is new to this business, what does he know?
"I've been doing it for nine years. I know more about it than he does. I always work really hard with whoever I get."
Louis also insisted he was a successful judge, despite only winning once in series two seven years ago
"Well I have won again, because as far I'm concerned, JLS won," the Irish music mogul told DigitalSpy today. "It's about what they do after the show is over. JLS had the best career.
"My three acts this year have the potential to get record deals. All three groups are here for it. It's a great showcase if you have something. And these lot do - they have a lot of it."
