NEW YORK -- Busy cancer patient Valerie Harper leads a class of 12 amateur hoofers in the upcoming 17th season of "Dancing With the Stars."
The cast was revealed Wednesday on ABC's "Good Morning America." For a show that has reached an increasingly older audience, ABC added an injection of youth with reality stars Nicole "Snooki" Polizzi of "Jersey Shore" and Ozzy's kid Jack Osbourne.
Ms. Harper has defied odds with her survival since being diagnosed earlier this year with terminal brain cancer. She recently filmed a movie role and joined a TV Land Nick at Nite reunion of "The Mary Tyler Moore" cast on "Hot in Cleveland."
A brain scan last month showed improvement for the 74-year-old former sitcom star, whose doctors say her cancer is getting close to remission. She will have her next scan in October.
Ms. Harper said that so far, she's not taking any precautions when she's rehearsing.
"[Pro partner Tristan MacManus] says, 'Do you want to get water?' Which is great because I don't drink enough water but [that's] not to do with the cancer ... [it's] not an impediment to dancing and I just try to stay healthy and continue to lose weight so I look halfway decent in the costumes," she said with a laugh.
Ms. Harper said of her decision to join the show: "There's a [Lee Ann Womack] country song [with the lyrics] 'when you get the choice you sit it out or dance/ I hope you dance.' "
Other contestants on the new season of "Dancing," which premieres Sept. 16, are Bill Nye, the "Science Guy"; "Pretty Little Liars" actor Brant Daugherty; former NFL wide receiver Keyshawn Johnson; singer-actress Christina Milian; actress Elizabeth Berkley; "High School Musical" actor Corbin Bleu; "Glee" actress Amber Riley; country comic Bill Engvall; and "King of Queens" actress Leah Remini.
Although still a ratings winner for ABC in its 16th season, the celebrity dancing contest has seen its overall audience decline and grow older, an issue for networks that get higher commercial ad rates for younger viewers.
"Dancing" will now air once a week on Mondays rather than Mondays and Tuesdays.
There are changes behind the scenes, too. There are new professional dancers, plucked from the show's troupe. Contestants are starting off with a four-hour rehearsal limit per day that will hopefully cut down on injuries and fatigue.
The pros were mixed on whether they liked the time constraint and said it could change as the season goes on and they have to do more than one dance per show.
"Now that we have a restricted time, I feel like we're gonna get more done," said Derek Hough.
"That I don't like," said Karina Smirnoff. "Four hours is tough."
"Every single time that last hour [of rehearsal] ends up coming up with both of us going, 'Oh no. It's not there yet,' " said her partner, Mr. Bleu.tvradio
