Hassie Harrison and Ryan Bingham, who play a couple on the TV show Yellowstone, said on Instagram that they are dating.

“More than a spark @hassieharrison,” Bingham wrote under the picture of the two kissing.

“I love you, cowboy,” said Harrison.

Harrison plays a ranch hand and barrel racer on Yellowstone, and Bingham plays Walker, a ranch hand who used to be in jail.

In the midst of rumors of Kevin Costner’s departure from the show, the actors took to social media to discuss their relationship.

On Instagram, the actors who play Sheriff Ramsey, Bob Kirkland, and Teeter, Jen Landon, showed their support for the couple.

Paramount Network President of Development and Production Keith Cox expressed optimism about Costner’s future involvement in the show during a panel at this month’s PaleyFest.

Yellowstone is a TV show about the Dutton family, who own the Yellowstone Dutton Ranch, which is the biggest ranch in Montana. The show’s plot is mostly about family problems that happen at the ranch and in nearby places like Yellowstone National Park, the Broken Rock Indian Reservation, and land developers.

Kevin Costner, Kelly Reilly, Luke Grimes, Wes Bentley, Kelsey Asbille, Cole Hauser, and Gil Birmingham are all in the cast of the show.

There are two more series in the Yellowstone franchise: 1883 and 1923. Matthew McConaughey will likely be in a third spinoff series.
