Emmy-winning actress Kathryn Joosten has died at age 72 following a bout with pneumonia while battling lung cancer.
TVLine.com reports that Joosten passed away Friday in Westlake Village, Calif., surrounded by family. A source tells ET that Joosten was undergoing chemotherapy treatment throughout the taping of the final episodes of Housewives, which led to her contracting pneumonia.
Desperate Housewives creator Marc Cherry told ET in a statement, "The character of Mrs. McCluskey was created for a single episode. We then cast Kathryn Joosten and she infused the part with so much feisty wit and curmudgeonly bravado, we knew we had to move her onto Wisteria Lane for the run of the series. I will forever miss her, as a co-worker and as a friend."
