Walsh's overs act Robinson has had a running argument with Barlow over his style and performances on the ITV1 talent show, but his mentor has joked that the Take That star is in no position to offer advice.
"Gary slagging of anyone's style is a joke. Err, hello? Have you seen his early Take That videos?" Walsh told the official X Factor site.
"Cycling shorts and chainmail vests? I rest my case. The outfits were atrocious; he was nearly naked in some of 'em!"
Walsh claimed that Barlow had "up to five people" doing his personal styling and grooming on the live shows and denied accusations that he is not as close to his acts as the other X Factor judges.
"I'm a mentor and my role is to guide my acts. The only reason Gary does extra stuff like taking his contestants running is because he needs to watch his weight," he teased.
