Words cannot convey how I feel about the people I got to work and create with over the seasons. I have made true life long friends."
"The support from the crew and the trust and dedication of the cast. The words I got to say and the woman I got to inhabit. It changed me. It lit me up. It challenged me in every way possible and I will forever be grateful for it," she added. "For Taylor Sheridan who took a chance on me and continued to write her in ways I got to feel on fire as an actor. Thank you Taylor."
Reilly ended with a message to the show's fans, writing, "Thank you the audience we made it for, for being on this journey with us. We really cared about making something special for you all...."
Grimes kept his message short and sweet as he bid farewell to his character Kayce Dutton and the show.
"End of an era," he wrote in an Instagram post. "Goodbye Kayce. You are a better man than I. To my yellowstone family, thank you for the experience of a lifetime."
Kelsey Asbille, who played Kayce's wife Monica, reflected on her onscreen partnership with Grimes.
"To share the screen with Luke over these past 7 years was such a dream," she wrote in the caption of an Instagram post.
