Arielle Kebbel is teasing what fans can expect from Y: Marshals.
The actress, 40, opened up about the upcoming Yellowstone spinoff during a recent interview with Entertainment Tonight, where she teased Luke Grimes’ return as the youngest son of John Dutton (Kevin Costner), Kayce Dutton. The new series will follow his life as he puts his ranching days behind him and joins the U.S. Marshals in Montana.
“Honestly, he’s such a badass,” Kebbel said of Grimes, 41. “Getting to work with him out on these rescue missions and we’re all carrying M4s and these huge rifles and we’re doing these big stunts. It’s so cool to work alongside him, but also see him in action, because it really is a totally different side to his character.”
“I know you got pieces of it in Yellowstone, but because this is picking up where that started so long ago, it’s exciting,” she added. “I think people are gonna like it.”

Kebbel also revealed that there will be cameos from some country music stars in Y: Marshals, which she found personally intriguing given her childhood.
“What’s really cool is our hang after our missions is at this local bar, and we have a stage there, and so we’ve had a few country artists come on, some up-and-coming, and some you will definitely recognize, and they’ve both been equally special,” she shared. “Because as a girl, I started listening to country music when I was 5 years old. I started riding horses at 5, I was at the barn every day, and I was picking my horse’s hooves listening to country music. So for me to be able to combine acting with country music is an absolute — it’s a dream.”
Y: Marshals was officially announced in May 2025 and will be a CBS original, airing on Sunday nights on the network. It’s one of several Yellowstone spinoffs in the works. Others include 6666, 1944 and The Madison, which are joining the already-debuted 1883, Lawmen: Bass Reeves and 1923.
According to the show’s official logline, the series sees Kayce Dutton “join an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.”
This new career trajectory is nothing surprising for fans of Yellowstone, which showed Kayce save Yellowstone Ranch by selling the land to Broken Rock Reservation in the series finale in December 2024.

In June, Grimes told PEOPLE that he thought it was “the end of the road” for his character when Yellowstone concluded before he knew there would be a spinoff.
“On the last day of shooting, I thought it was my last day as Kayce. It was over to me,” he says of the conclusion to season 5, which aired in December. “It was seven years of playing a person that I’ll never see again, except for having his hat and jacket in my closet. It wasn’t until probably three or four months after that that everything started aligning for the [spinoff].”
When the idea of continuing Kayce’s storyline came along, the Fifty Shades actor explained that he “definitely wanted to make sure to give it a real story and make it interesting and make it believable.”
“If it was just like, ‘Well, he’s happy’ — we’re just going to watch him be happy? That’s not very cool,” he noted. “But I’ll say this: the idea that was pitched to me is very, very good and very interesting and it really roped me in and I think it will rope the audience in as well.”
“It will be weird,” Grimes later admitted of carrying on the character without the original Yellowstone cast, who he called “family.”
“There’s going to be some familiar faces, but there’s going to be a lot of new faces too, so we’ll see how that all feels.”
