The 45-year-old has been offered to appear on the talent show alongside Sharon Osbourne, reported Daily star.
"Yes I was asked to do it again. I think they think that because my tour's finished I'm going to be bored, but I'm never going to be that bored. Sharon Osbourne gets 1.5 million pounds for it, I've heard. If she's worth one and a half, what am I worth? Three? Three and three quarters ?" Gallangher said.
"I've not got anything against the show, I just don't want to be on the television every Saturday night," he added.
