Paul Stanley revealed what he REALLY thinks of Peter Criss.

In his new book, Backstage Pass, he got candid about his relationships with KISS bandmates, Ace Frehley and Peter Criss.

When it comes to Frehley, Stanley said, it was “nice” to have him “back in a larger capacity in [his] life.”

However, with Criss, Stanley had some not-so-kind words. “Peter unfortunately is a different story,” he wrote. “I don’t think Peter has any life. He seems consumed by some kind of reality that his wife tells him. He’s always been negative and always maintained an us-against-them mentality. I don’t want that in my life.”
