Faith Hill truly cherished her "a once-in-a-lifetime experience” shooting the “Yellowstone” prequel series “1883” and shared that she even became a little depressed when the six-month filming schedule for the Paramount+ drama was done.

"I went through a little bit of a depression, I have to say, for a couple of weeks I was just really sad," Hill told ET in an exclusive interview. "There was something about that schedule too that was severe and grueling but it became so much a part of our lives for almost six months."

Hill stars opposite her husband Tim McGraw in the Western Limited series which dropped in December 2021 on the streaming platform. “1883” follows the Dutton family who left Texas to seek a better life in Montana. Hill and McGraw play Margaret and James Dutton, founders of the Yellowstone ranch.

Since they married in 1996, Hill and McGraw have worked together multiple times, recording music and going on concert tours. While both have acted in various separate projects, “1883” was the first production that brought the couple together in a single acting project.

Hill said she and her husband eagerly jumped at the chance of playing the Dutton couple knowing that it was an opportunity they could not pass up.

"We've been asked to do things together before, the reason for this one, this particular one, was because of the material, we couldn't pass it up. It felt like a blessing, we felt so lucky, honestly, to have that fall into our lap," she told the outlet.

The “There You’ll Be” singer earlier revealed that she and her husband did not practice their lines at home to keep the scenes as authentic as possible.

“We’ve been married 26 years. We’ve never done anything like this together. Tim’s a legit actor, and I felt the only way to bring it as authentically as I possibly could, was to experience James and Margaret for the first time on set,” Hill told The Hollywood Reporter earlier this month. “It would have been hard to separate the two for me. It seemed to work because Tim still surprised me when we were working together — he did things as James I didn’t expect from him. I needed that in order to be as natural as possible,” she added.
