The star, who plays the younger version of John Dutton in the hugely

popular western, has been dating his TV meteorologist partner for two years now.

On his Instagram, he shared a video across two slides of his now fiancé getting emotional

at a restaurant as a band of musicians performed, with a sparkly ring on her finger. The caption for the post, which also included a photo of them embracing outdoors, reads: “For the last 2 years in Every Way and Every Day this beautiful soul has made me and my life better, deeper, and more whole.

“I am so grateful and thrilled she said ‘Yes’. I WAY love you Brianna. & Thank You to our families and all the people and places that made this come true. I am absolutely aware I got crazy lucky.”

Brianna shared a compilation of the videos with a photo of her own to her Instagram, writing: “Almost 2 years ago this fall, and with no expectations, Josh walked into my life.. and we knew almost immediately we had each found our person in a way we’ve never experienced- on every level.

“This was the easiest and best question I’ve ever answered. So, here’s to forever with my love, my best friend. I can’t wait to keep living this life with you.”

At the end of May, Yellowstone actors Hassie Harrison and Ryan Bingham tied the knot at a cowboy-themed intimate ceremony in Dallas, Texas.

The second half of Yellowstone’s fifth season is on the way. It’s has now become the final season after Kevin Costner announced his departure, and he’s since spoken about the behind-the-scenes drama that led to his decision.
