Brolin revealed her slightly less unique nickname in his caption. He wrote, “Dearest Ladies and Gentlemen, I would like to introduce our little girl Westlyn Reign Brolin (Bean). Mama Kathryn was stellar during this miracle birth and Bean is a flawless gem through and through. 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.”
Although this is the couple’s first child together, Brolin shares two adult children with his ex Alice Adair—Eden Brolin (24) and Trevor Brolin (30). This is Kathryn’s (31) first child.
Congratulations to the new family.
