Leah Remini, Valerie Harper joining "Dancing with the Stars"?

The new cast of "Dancing with the Stars" won't be announced until next week, but speculation is already swirling about which celebs will be lacing up their dancing shoes this season.

According to reports, two of those stars are Leah Remini and Valerie Harper.

Sources close to "DWTS" told The Hollywood Reporter that Remini will be hitting the dance floor. Us Weekly and TMZ have also reported the news.

Remini made headlines earlier this summer after she parted ways with the Church of Scientology. Following her departure, "The King of Queens" star filed a missing persons report for Scientology leader David Miscavage's wife, Shelly, which Los Angeles police later deemed "unfounded."

Harper's involvement in "DWTS," meanwhile, was reported Wednesday by TMZ. According to the site, the star of "The Mary Tyler Moore Show" and "Rhoda" has been paired up with dancing pro Tristan MacManus.

The 74-year-old actress revealed earlier this year that she had been diagnosed with terminal brain cancer. It was said at the time that she had as little as three months to live, but her prognosis now appears to be more promising -- in a "Today" show segment Thursday morning, Harper's doctor said she may have beaten back the cancer for now.

"I'd say that we're getting pretty close to a remission," neuro-oncologist Jeremy Rudnick told Meredith Vieira, adding, "It defies the odds." The revelation is part of an hour-long documentary about Harper's battle with cancer that will air Sept. 19 at 10 p.m. ET on NBC.

Along with Harper and Remini, TMZ also reports that reality TV's Nicole "Snooki" Polizzi, "Glee" star Amber Riley, actress Elizabeth Berkley and singer Christina Milian will appear on the show.

ABC has not commented on any of the casting speculation. The "Dancing with the Stars" season 17 cast will officially be announced Sept. 4 on "Good Morning America."
