Jason Aldean and his wife, Brittany, are the proud parents of a newborn baby girl. Navy Rome was born Monday, Feb. 4, at 12:45PM.

Brittany Aldean shared details of their new daughter on social media on Monday night, saying she weighed 7 lbs. and 12 oz. "We love you so much baby girl," she writes. Jason shared the same photo and a similar caption on his social media at the same time, adding that Navy arrived "looking identical to her older brother. So excited to watch what life has in store for this little princess."

Both have been open with details about the baby and their process of preparing. On Instagram the social media influencer shared her professional maternity photos, as well as pictures of the new baby's nursery.

Peek Inside Baby Navy's Nursery: 

The couple married in Mexico in 2015, and they welcomed their first child together, son Memphis, in December of 2017. They announced that they were expecting their second child on July 10, 2018, with a photo of 7-month-old Memphis lounging in a onesie that read: Big Brother.

The couple underwent In-Vitro Fertilization after they struggled for a year and a half to conceive Memphis, and they turned to IVF again when they decided to have another child so soon afterward.

Aldean and Brittany revealed they were expecting a girl in a baseball-themed gender reveal in August, and Aldean shared that they had decided to name her Navy Rome Aldean at a celebration for his most recent No. 1 single, "Drowns the Whiskey," in January.

"Like with Memphis, we made a list of names that we liked, and we'd go back every once in a while, and names that had fallen off we'd take off the list," Aldean told reporters. "Britt wanted to name Memphis 'Roman' and I wasn't really feeling it. So when it came time for Navy, she asked, 'Do you care if we give her the middle name Rome?' and I was like, 'Works for me.'"

Aldean also has two older daughters, Keeley and Kendyl, from his first marriage.
