Lady Antebellum is adding another baby to the group. This time it's trio member Dave Haywood and his wife Kelli.

Lady A announced the exciting news on Facebook. Says the band, "So excited for a new Baby A on the way in Sept! And it's a boy!!! -Dave & Kelli"

That means that Hillary Scott's sweet baby Eisele will have a fellow baby friend to lay with during the band's tours. It should essentially be an endless play date on their tour bus.

Haywood and the mama-to-be tied the knot in April of 2012, and their little boy will be the couple's first child. Charles Kelley and wife Cassie are the only couple of the three to be baby-less. They were married in 2009.

Congrats to the excited and soon-to-be parents!
