Morrissey, who made headlines for his relationship with Dennis's then-wife Holden in 2000, told Metro that he had no interest in reading the comedian's account of the incident.
He said: "I honestly don't care. It's a backhanded compliment. They were using me in newspapers to promote that book, so that says it all."
Morrissey accused Dennis of being "grossly unfair and unprofessional" for exploiting his fling with Holden for book sales.
"I think it’s grossly unfair and unprofessional to blow the whistle on your contemporaries in return for money," he commented. "I wouldn't write about my celebrity friends and 'whoops, there goes my trousers'. Those sort of books sell but I've got other ways of making a living."
