Valerie Harper, who, in March, announced that she was diagnosed with leptomeningeal carcinomatosis -- a rare form of cancer where cancer cells spread into the membrane surrounding the brain -- is reportedly set to compete on “Dancing with the Stars.”

After her diagnosis, doctors had given Harper just three months to live as the cancer is incurable. But according to a TMZ report, the 74-year-old actress is healthy and has started training with her dancing partner, Tristan MacManus.

"Cancer makes real what we try to obscure from ourselves,” Harper told People in March, after her diagnosis. “We spend our lifetimes thinking, 'I'm never going to die.' But cancer says, 'Hey, not so fast.'"

"I don't think of dying. I think of being here now," she said at the time.

According to the TMZ report, other contestants on “Dancing with The Stars” include actress Leah Remini, "Jersey Shore" alum Nicole "Snooki" Polizzi, actress Elizabeth Berkley, "Glee" star Amber Riley and actress-singer Christina Milian.

Although sources close to the production confirmed that Remini is on board, ABC, which airs "Dancing with the Stars," has not commented on the casting rumors. But, Riley’s Instagram account indicated that she has a major announcement on the horizon, and various media reports speculate it might be about her taking part in “Dancing with the Stars.”

“HUGE announcement next week hehehehehe! Can't wait to share y'all,” she posted on Wednesday.

The season 17 cast of “Dancing with the Stars” will be officially announced on Sept. 4 on “Good Morning America,” and the show will be telecast from Sept. 16.

The ballroom dancing competition has brought in some changes, which includes a two-hour single airing every week, and each week will see one couple eliminated from the show based on votes from viewers and judges' scores.

The show will be hosted by Tom Bergeron, best known as the host of America's Funniest Home Videos, and Brooke Burke-Charvet, the winner of season 7 of “Dancing with the Stars.”
