Paul Stanley's mom died on Saturday. She was 88.

Paul Stanley is mourning the loss of his mother, Eva Eisen, who died on Saturday at the age of 88.

Stanley, whose real name is Stanley Eisen, says, "My mother found so much pleasure and fulfillment in all the various types of music that she so loved. It was through her that I, too, found that same passion. She lived long enough to see, enjoy and love an extended family that included her children, grandchildren and great grandchildren. She found numerous ways to contribute to her community and was appreciated and loved by those who knew her. My mom was the matriarch of our family and words cannot express our loss."

The three members of KISS issued a statement saying, "From the earliest days of KISS until recently, Eva was always seen by fans at New York-area shows. We send our deepest sympathies to Paul and his family. Our thoughts and prayers are with you."

Despite the loss, KISS performed on Saturday in Mexico City, but it is not known if Monday's show in Monterrey, Mexico will go on as scheduled.
