Zac Brown Band's Clay Cook and his wife Brooke are expecting their second child! The artist recently shared the exciting news with fans via social media.

On Wednesday (Jan. 24), Cook posted a photo on Instagram to announce that his family is growing. It's a picture of himself, his wife and their first child, Charlie, reading a Berenstain Bears book, New Baby.

"Our book-loving kid has a new favorite. I think it’s safe to say he’s pretty excited about this one. So happy to announce that Charlie has a sibling coming this summer!" Cook writes. "We couldn’t feel more lucky to be growing our family."

Cook and his wife welcomed Charlie, their first child, to the world in November of 2016. The couple has been married since 2014.

The Cooks' new baby won't be the only new Zac Brown Band family member coming into the world in 2018: Fellow ZBB member Coy Bowles and his wife are also expecting their second child. The couple revealed their big news in November.

As Zac Brown Band's lead guitarist, Cook is preparing to launch Down the Rabbit Hole Live: Zac Brown Band 2018, the band's upcoming tour, in June. On Sunday (Jan. 28), the band will be competing for Best Country Duo / Group Performance at the 2018 Grammy Awards.
