Jacob Davis welcomed his newest baby girl to the world over the weekend. The country up-and-comer announced the birth of his second daughter on Twitter on Monday (Sept. 18).

Baby girl Lane Elizabeth, according to a press release, was born on Sunday (Sept. 17), weighing 8 pounds, 10 ounces. Davis' tweet about the big news includes an endearing photo of all three of the women in his life -- Lane, daughter Percy and wife Whitney -- with the hashtag #allmygirls. Percy was born on Christmas Eve in 2015.

The arrival of Davis' new daughter likely came as a surprise to fans, as the singer did not publicly reveal his wife's pregnancy. The artist has been busy on the road as of late, including making his Grand Ole Opry debut; his song "Down to Earth" was inspired by his wife and first daughter.

“I think about even artists 10 years ago and not having FaceTime,” Davis tells Taste of Country about parenting from the road. “You think, ‘How did they do that?’ It’s every day I see my wife and my little girl and she sees my face and hears my voice.”

In March, Davis released his first single, "What I Wanna Be." He is working on his first full-length album with Black River Entertainment, the label he signed with in 2016. For tour information, check out Davis' official website.
