Congratulations are in order for Clay Walker, and his wife Jessica: The couple recently welcomed their fourth child, a boy named Ezra Stephen Walker.

Walker announced the arrival of his family's "newest angel" in a post to his Instagram account on Friday (Nov. 3).

"Ezra Stephen Walker has arrived! He and Mama are healthy and home," Walker writes. "Blessed ... thank you for your prayers always."

Walker and wife Jessica announced the big news that they were expecting on Instagram just ahead of the 2017 ACM Awards in April. Photographers snapped some shots of Walker kissing his wife's stomach as the couple walked the red carpet at the event.

“Jessica and I are beyond excited to be expecting a new addition to our loving family,” Walker said in a press release announcing his wife's pregnancy. "There is no greater challenge nor achievement than being a father, and I am beyond blessed and humbled to be one six times over. 2017 is certainly going to be a great year filled with our family growing and new music, and I am ecstatic about both!"

In addition to baby Ezra, Walker and his wife have three other children together: Elijah Craig, Mary Elizabeth and William Clayton. From a previous marriage, Walker also has two teenage daughters, MaClay DaLayne and Skylor ClayAnne.

It's been an exciting week for Walker, who performed the National Anthem at Game 5 of the World Series. His Houston Astros brought home the Commissioner's Trophy for the first time ever this year.
