Jason Aldean and wife Brittany Kerr have announced the arrival of their second child together! Navy Rome Williams, a girl, was born on Monday (Feb. 4).

According to an Instagram post from Aldean, Navy weighed 7 lbs., 12 oz., when she was born, "and look[ed] identical to her older brother." Kerr's Instagram post notes that Navy was born at 12:45PM.

"Today our family became complete," Aldean writes. "So excited to watch what life has in store for this little princess."

Aldean and Brittany's newest bundle of joy joins big brother Memphis in the Aldean family, as well as older sisters Keely and Kendall, both from Aldean's first marriage. Aldean and Kerr shared the news of her second pregnancy in July of 2018, telling fans that Memphis -- who was born at the end of 2017 -- would be a big brother soon and using the hashtag #aldeanpartyof6.

“We created a list and both were throwing names in there throughout the past few months, and Navy happened to be the one we liked the most,” Kerr tells People of her new daughter's name. “I chose Rome because I really wanted to name our son Roman but Jason wasn’t a fan so this was my way of sliding that in there!”

Aldean and Kerr have been married since March of 2015.
