Congratulations are in order for Jimmy De Martini and his wife Stacey: The Zac Brown Band member is now a father of four!

Stacey gave birth to a baby girl, Jonelle -- the De Martinis' first daughter! -- on April 4. She weighed 6 pounds, 5 ounces at birth.

The Zac Brown Band shared De Martini's happy news on Instagram on Wednesday night (April 12). The band posted a sweet photo of the De Martinis' three sons -- 9-year-old James, 6-year-old Joseph and 1-year-old Jackson -- dressed in baseball gear and holding their new sister.

De Martini is the third ZBB member to have a child in recent months: Coy Bowles and his wife Kylie became the parents of a baby girl, Hattie, in October, and Clay Cook and his wife Brooke welcomed a baby boy, Charlie, in November.

Zac Brown Band are getting ready to release a new album, Welcome Home, on May 12; two of the songs that ZBB have shared from the record, "My Old Man" (the album's first single) and "Family Table," have a family focus.

On the same day as Welcome Home's release, the band will begin its 2017 Welcome Home Tour, which will keep them on the road through the end of October; the trek includes a stop at WE Fest 2017 in August.
