The Civil Wars has a teeny new recruit!

Joy Williams, who as one-half of the hitmaking duo scored two Grammy Awards this year, welcomed her first child, a son, with hubby Nate Yetton on Saturday.

The proud mama tweeted the news, in which she also revealed her tot's oh-so-distinguished name.

Ladies and gents, let's all welcome...

Miles Alexander!

"Now I really know what love at first sight means after meeting my son, Miles Alexander," the gushing new mom wrote. "Born yesterday, all happy and healthy. xo."

It's certainly been a year of big milestones for the brunette songbird. Shortly after announcing her pregnancy, she and her Civil Wars collaborator, John Paul White, won a pair of Grammys, for Best Country Duo/Group Performance and Best Folk Album.

The duo also teamed up with Taylor Swift to record a song for The Hunger Games soundtrack, "Safe & Sound."

Talk about a rockin' year—congrats to the proud new parents!
