Now entering its 17th season, the dancing competition will shift to a single, two-hour airing per week, with Valerie Harper, Jersey Shore's Snooki and Showgirls star Elizabeth Berkley also tipped to appear.
Remini's inclusion is all the more notable given her parting of ways with the Church of Scientology for questioning its treatment of church members and allegedly the autocratic leadership of David Miscavige.
The situation became all the more strange when Remini filed a missing persons report for Miscavige's wife, Shelley, which the Los Angeles Police Department later deemed "unfounded" after checking on her.
"No one is going to tell me how I need to think, no one is going to tell me who I can, and cannot, talk to," Remini told People about her reasoning for leaving the controversial religion.
Brooklyn-born Remini, 43, had been a member of the church for three decades, following in the footsteps of her mother and Angelo Pagan, who had also been members.
ABC has declined the comment on the story ahead of its official cast announcement on Good Morning America, September 4, 2013. Season 16 was won by the American Idol singer Kellie Pickler and her professional partner Derek Hough.
