Josh Brolin shares heartwarming Instagram post for wife Kathryn on their seventh marriage anniversary

The couple completed seven years of togetherness, recently.

The 'No Country for Old Men' actor wrote on Instagram: "It's in moments like these that move me -- our foreground assaults of any backdrop. It could be us then or us now, the kisses that create us. They are all at once sexy and smart and more stripped down than I've ever known us to be."

"You're a force who demands the experience of deepening, and I thank my lucky stars that you chose me to want to share all this with. Fierce ain't for everyone. Most people want their cake and their icing left at the back door and they don't want you to knock too loud when you leave it. We are a more feral bunch," he said in his heart-touching message posted on Instagram.

"You can see it in our little girls, as they already embrace the dirt clod voices that are theirs and not the masquerading whispers of that weakest vocabulary word: etiquette. Kindness and the surety that every voice is unique and beautiful and worthy and has the capacity to sing becomes us," he said.

Brolin married his third wife Kathryn in 2016.

The couple share two daughters, Westlyn, 4, and Chapel Grace, 2.

Brolin was earlier married to Alice Adair and Diane Lane, both Hollywood actresses.
