The 'Avengers' star revealed the name of his daughter, Westlyn Reign Brolin, in his post.

Josh Brolin is now a father of three.

On Sunday, the 50-year-old Avengers: Infinity War star revealed on Instagram that he and his wife Kathryn Boyd welcomed their first child together.

Brolin posted an adorable video of his newborn daughter bundled up, where he could be overheard saying, “You’re so sweet,” to the infant.

The video was accompanied with a cute caption: “Dearest Ladies and Gentlemen, I would like to introduce our little girl Westlyn Reign Brolin (Bean),” said the actor in revealing the baby’s name.

“Mama Kathryn was stellar during this miracle birth and Bean is a flawless gem through and through,” continued the proud new dad. “We are blessed to the core and appreciate so much the love and support during this pregnancy from ALL who have partaken in our journey, directly and/or indirectly.”

The Deadpool actor married Boyd, who was his former assistant and a model, in September 2016.

This is the third child for Brolin, who shares two children with his first wife, actress Alice Adair. He also was previously married to actress Diane Lane.

The baby news comes as Brolin is gearing up to reprise his role as Thanos in the fourth and final Avengers film, which is due out in May.
