Actor Josh Brolin marked 10 years of togetherness with wife Kathryn Boyd Brolin on 26 September 2026, sharing an emotional tribute on Instagram that called her his 'romping partner' and compared their bond to 'young, stupid puppies out on a beach walk chasing birds.' The post, accompanied by a romantic monochrome photograph of the couple sharing a kiss, quickly drew attention from fans and admirers worldwide.

What Josh Brolin wrote

In his caption, Brolin reflected on a decade of shared life with characteristic warmth and wit. He wrote: 'In ten years I've never seen her without a costume, heard her without an accent, nor ever lived far outside the radius of her circus. Growing up all I wanted was to find a playmate, someone to share the sandpit of this life with sharing whatever the imagination can conjure.'

He added: 'Ten years and we're still at it, like a couple of young, stupid puppies out on a beach walk chasing birds. My romping partner — till death do us part....#olé P.S. I'm watching La Strada if you want to join me?'

Josh and Kathryn: Their Story

Brolin and Kathryn Boyd, a former model and one-time assistant to the actor, began dating in 2013 — the same year his divorce from actress Diane Lane was finalised. The couple wed in 2016 and announced in 2018 that they were expecting their first child. They now share two daughters together.

Notably, the anniversary post arrives as Brolin remains one of Hollywood's most commercially active performers, with recent credits spanning the Dune franchise and Brothers.

Josh Brolin's Personal History

Brolin was previously married to actress Alice Adair from 1988 to 1994. He was subsequently engaged for six months to actress Minnie Driver, before marrying actress Diane Lane on 15 August 2004; that marriage ended in 2013. His relationship and marriage to Kathryn Boyd marks what appears to be the most enduring chapter of his personal life.

Career in Brief

Born to acclaimed actor James Brolin, Josh first came to widespread attention as a child star in the 1985 adventure film The Goonies. His adult career gained critical momentum with No Country for Old Men, before he achieved global recognition playing the villain Thanos in Avengers: Infinity War and Avengers: Endgame within the Marvel Cinematic Universe (MCU). His filmography also includes Sicario, True Grit, Dune, Dune: Part Two, Dune: Part Three, and Deadpool 2, among others.

As the couple enters their second decade together, Brolin's tribute suggests that, for all his Hollywood milestones, the 'sandpit of this life' he shares with Kathryn remains the one he values most.
