Dancing With the Stars may not officially announce its season 17 cast until Sept. 4, but new reports came out Wednesday about many of the celebrities that will participate on the show.

Valerie Harper, the 74-year-old sitcom legend, will be participating in the new season of Dancing With the Stars this fall, according to TMZ.
