Valerie Harper joins 'Mary Tyler Moore Show' reunion on 'Hot in Cleveland'

Seems just like old times. The cast of "The Mary Tyler Moore Show" will reunite on the small screen, and they've got none other than Valerie Harper making it to the party -- a sure-to-be-poignant, funny and treasured moment in the wake of her revelation that she has been diagnosed with terminal brain cancer.

Per Deadline, the sitcom confab is set to happen in an upcoming episode of "Hot in Cleveland," where series star Betty White will be joined her old "MTMS" pals Mary Tyler Moore, Cloris Leachman, Georgia Engel (who's already got a regular guest stint on the show), along with Harper.

This will mark Moore's second appearance on the show and, reportedly, the gals' first reunion since "MTMS" bid adieu in 1977.

In the episode, which is supposedly set to shoot on April 5, White's old cohorts will play her former teammates on a squad called GLOB -- aka The Gorgeous Ladies of Bowling -- who reunite years after a falling-out over inflated egos. (Is everyone feeling an awesome strike, here?)

Earlier this month, Harper announced that she had been diagnosed with leptomeningeal carcinomatosis -- a rare cancer attacking the fluid-filled membrane enveloping the brain -- and that doctors had given her between three and six months to live.

But the actress says she's determined not to let her illness define her remaining days.

"I'm not dying until I do. I promise I won't," she told the TODAY show two weeks ago. "More than hopeful, I have an intention to live each moment fully."
