Yellowstone's Luke Grimes And Kelsey Asbille Gush Over Their Wonderful Partnership On The Show

Before "Yellowstone," Luke Grimes was probably best known as Christian Grey's brother, Elliot, in the "Fifty Shades of Grey" film franchise, while Kelsey Asbille appeared on "One Tree Hill" and MTV's "Teen Wolf" series. Now, coming together as Kayce and Monica, the actors couldn't be happier with their behind-the-scenes dynamic, which includes always keeping things light on the drama-fueled set.

"It's always easy with those two [characters]," said Grimes. "I feel like we don't have to try to keep it light, and that's been great. Neither one of us take ourselves very seriously, although we take our work really seriously."

Asbille added, "There's so much trust and comfort there. It's a wonderful partnership."

That friendship has led to a lot of laughs on set too, including plenty of running jokes that Asbille declined to reveal. "It wouldn't be appropriate [to share]," she said with a chuckle.

Season 5 of "Yellowstone" airs Sundays at 8 p.m. ET/PT on the Paramount Network.
