Actor Josh Brolin, wife Kathryn Boyd welcome first child together

Congratulations are in order for Marvel star Josh Brolin and his entrepreneur wife Kathryn Boyd!

On Sunday, Nov. 4, 2018, the Avengers: Infinity War star took to Instagram to reveal that the happy couple have welcomed their first child together, a baby girl named Westlyn Reign Brolin.

"Dearest Ladies and Gentlemen, I would like to introduce our little girl Westlyn Reign Brolin (Bean)," the proud dad wrote to his 1.6 million followers, captioning an adorable clip of their newborn daughter smiling while fast asleep. "Mama Kathryn was stellar during this miracle birth and Bean is a flawless gem through and through." 

Brolin added, "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. #beanlove."

For her part, Boyd shared the same video, writing, "Our family's newest (and tiniest) member. Westlyn Reign Brolin, I love you so much already. Nothing compares to this… nothing. My heart is totally different forever. @joshbrolin thanks for this little life of ours."

As Nicki Swift previously reported, Brolin, 50, first announced that he and Boyd, 31, were expecting their first child together in late May 2018. "There's a new sheriff in town, and she's no bigger than a sweet potato. Hang on to your hats," he wrote on social media at the time, captioning a snapshot of his wife showing off her baby bump. The Deadpool 2 star added the hashtags, "#jbkbstucktogether #lilbeanterritory #loveisaslovedoes."

The proud parents tied the knot in September 2016. Brolin, who divorced actress Diane Lane in 2013, is also a dad to daughter Eden, 24, and son Trevor, 30, from his previous marriage to Alice Adair (via E! News).

Brolin and Boyd aren't the only celeb pairing to share an exciting baby announcement this weekend. On Sunday, Nov. 4, The Real Housewives of Atlanta star Kenya Moore welcomed her first child with her husband, businessman Marc Daly. As the reality TV star explained to People magazine, the married pair named their baby girl Brooklyn Doris Daly for two special reasons: "Brooklyn because that's where we met and fell in love, and Doris after my grandmother who passed away last year and who raised me."

Congrats again to Brolin and Boyd on their baby news!
