The Liverpudlian singer said he had been persistently hounded by a women in her 40s.
"She's an older lady," McCabe told the Daily Star. "In her late 40s, I think - and she won't leave me alone.
"She’s got my mobile number and keeps sending me pictures of herself with her t**s out."
McCabe also claimed he was disappointed by criticism of his band's recent You Can Do Anything album.
"I wanted it to go to No.1 and sell millions. I'm gutted," commented the frontman.
"Maybe it's just our time to fall out of favour. But we'll just keep gigging. That's what we love doing the most."
