An insider tells People magazine Harper will be joined by Mary Tyler Moore and Cloris Leachmann for the guest appearance. "The cast is really excited to have Valerie guest star. They feel she is a true icon, and they are touched by her story,” the source says.
Deadline.com reports the episode will involve the ladies reuniting their bowling team, GLOB: The Gorgeous Ladies of Bowling. Filming will begin on April 5. Harper, 73, has not commented.
Harper is suffering from leptomeningeal carcinomatosis, or cancer in the fluid-filled membrane that surrounds the brain. "This is a really complicated condition. The spinal fluid is a collection of fluid that's being circulated [through the brain] kind of like a sink. The fluid itself is growing cancer cells so they are multiplying in there. Those cells start to coat the brain,” explained Harper’s neuro-oncologist, Dr. Jeremy Rudnick.
The actress is undergoing chemotherapy to slow down the disease. "I don't think of dying," Harper told People earlier this month. "I think of being here now."
