Country crooner Dierks Bentley now has a baby boy.
The "What Was I Thinkin'" singer and his wife, Cassidy, welcomed son Knox on Wednesday in Nashville, his rep told People.
The little guy, who joins older sisters Evalyn Day, 5, and Jordan Catherine, 2, weighed in at 6 pounds, 12 ounces, the rep said.
"Knox met his big sisters Thursday morning. Cassidy is doing great!" the singer's rep added.
Bentley, 37, and his wife married in 2005, and announced the baby news last April. In June, while he was touring with Miranda Lambert, Lee Brice and Thomas Rhett, he revealed the child's gender in a video message.
By Thursday morning, he had posted several tweets sharing the big news and thanking fans for their congratulations. He also went into a bit more detail about his son's birth process too.
"well... our boy knox is here! about to have the best tasting cold beer of my life! so proud of my wife. she rocked it. crazy stuff. #beerme," he tweeted, adding, "mad respect for doctors, nurses and everyone at hospitals. can't believe y'all do that day in and day out. hard work making miracles happen."
"could have done without seeing my son's 'stick out' (as my girls call it) covered in blood. ouch! makes you question the circumcision thing," he continued.
Here's hoping he doesn't write a song about that particular detail ....
