Get out your tissues in advance of tonight's "Yellowstone" finale, advises Kelly Reilly, who plays wild child Beth Dutton on the show. Before tonight's show, Reilly posted a farewell of sorts on Instagram, but didn't allude to the spinoff reportedly ...

With the clock winding down to the final episode of Paramount Network’s “Yellowstone,” series star Kelly Reilly took to Instagram Sunday to confirm that the Dec. 15 episode is in fact the finale to the mainline series.

Only hours before the premiere of the last episode of Paramount Network’s Yellowstone, leading lady Kelly Reilly took to Instagram with a message for her colleagues as well as the Taylor Sheridan drama’s devoted audience.

And then, last week the news came… it was reported by Deadline that Kelly Reilly and Cole Hauser would be reprising their roles as Beth Dutton and Rip Wheeler in a modern day spinoff series that would also feature some more of the current cast.

After Deadline reported that Cole Hauser and Kelly Reilly closed deals for a 'Yellowstone' spinoff, the Rip Wheeler actor is staying tight-lipped.

There’s been a lot of confusion about the future of Yellowstone. Paramount Network is calling Sunday’s episode a season finale as opposed to a series finale. However, Paramount is prepping spinoffs and continuations.
