Jason and Brittany Aldean seem to prefer baby names that run on the unique side, having chosen a somewhat unconventional one for their first child together, Memphis. They're apparently continuing this trend with the name they've chosen for their unborn daughter: Navy Rome Williams.

Navy is due in February.

Brittany revealed the little girl's name on Sunday (Nov. 4), posting a picture of what appears to be the trappings of a baby shower, with the name "Navy" written in cursive neon. She then teamed up with Jason's second daughter, Kendyl, in her Instagram Stories to both confirm the first name, and also announce the full shebang.

Fans responded enthusiastically, calling the name "pretty," "unique," and "so cool" in comments on the social media post. There's no word yet on if there is any particular story behind the name—something many fans queried, as well.

As for the shower, based on Brittany's Instagram Stories, it appeared to be held at home, with plenty of food and family on hand. Aldean is seen filling his plate with a variety of goodies, while Memphis toddles about unsteadily waving a balloon.

The shower even hosted a few famous friends, too, with Kane Brown, Shay Mooney of Dan + Shay, and Dee Jay Silver all coming by to fete baby Navy.

The couple first announced little Navy was on the way, when they shared in July that they were expecting again. A fun gender reveal video followed, in which fans and Aldean's two older daughters were treated to the news that another girl would be joining the family. Navy's big brother, Memphis, will turn 1 in December.

The couple are also keeping busy with another project: They're selling their current residence and building their dream house on a piece of land in Tennessee, in order to accommodate their growing family for years to come.
