Walsh is the only judge on the ITV1 show not to have an official Twitter account. The Irish reality TV star said that he may be forced to get online, but confessed that if it was up to him, he wouldn't get involved.
"I'm not on Twitter. I've never been on Twitter," said the Irish music mogul.
"I don't look at Twitter. Honestly."
When asked whether he was being pushed to sign up with an account, he added: "I might have to, but I don't really want to do it."
Walsh is mentoring the Groups category on this year's X Factor, which includes MK1, GMD3 and Union J.
The Live Shows start tonight (October 6) at 8pm on ITV1.
