Lifetime renewed “Army Wives” for a seventh season last week, as previously reported, but now it appears that the show may have to carry on without its star, Kim Delaney.

Deadline.com reports that Lifetime and ABC Studios, which produces the series, would not confirm the return of any cast members, holding off on an announcement until closer to the beginning of production. The production schedule has not been locked in yet, the report notes.

“Speculation about Delaney possibly exiting ‘Army Wives’ has been percolating for a while,” the story reports. “This past season, ‘Army Wives’ introduced a new cast member, Kelli Williams, which was considered a potential move to ensure a smooth transition and fill a void if Delaney were to leave.”

The future of other cast members is also in limbo, the story reports. Other than Williams, who is locked in, and Catherine Bell, who signed a new two-year agreement in May, the cast members reportedly had their contracts expire at the end of season six and do not yet have deals for season seven.
