Gene Simmons wouldn’t leave his wife if she cheated on him.

In a new interview, the Kiss rocker explained, “Would I ever leave if Shannon dilly-dallied like I had? No. Absolutely not, that will never happen. This will be the only marriage I ever have because my definition of marriage isn’t based on that stuff, it’s based on somebody who in a real sense will give their life for you. We’ve proved it in creating two new, wonderful, amazing forms of life, our kids. Nobody else can do that. At the end of the day my life will be judged by Shannon, and Nick and Sophie.”

The 74-year-old has been married to model/actress Shannon Tweed since 2011 but they have been together since 1983.
